Comet NeoWise Visible in July

Comet Neowise is bright and now easy to see.  I took this photo by Ft. Steele on Tuesday morning at 1:30am.  To see the comet, I’d recommend to go between midnight when it gets fully dark, until 3:30am when the Northern sky brightens with dawn.  Otherwise the faint streak of the comet is difficult to see against the glowing sky.  Binoculars make it brighter and allow you to see the pale-blue ion tail and pale-yellow dust tail, but it’s clearly visible by eye.

The photo shows Comet Neowise, looking North from Ft. Steele on Tuesday around 1:30am.  Lakit Mountain to the bottom right side with constellation Auriga hidden behind it, Capella the bright star there.  It was taken through a 28mm wide-angle lens.  The green glow along the horizon is the Northern Lights, which were slightly active that night.  According to NOAA, on their 9-point Kp scale it was a minor geomagnetic storm level 3.

Here’s the comet two days later, on Thursday morning at 2am.  Looking at the background stars, notice it’s shifted slightly upwards and to the left from the first photo.  Photographed with a more sensitive 28mm f/1.8 lens.  The comet looks a bit brighter, a white nucleus at bottom, with a pale-blue ion-jet going straight up, as well as a wide pale-yellow dust tail curving back.  Again, along the bottom right you can see Lakit Mountain with trees silhouetted in the red glow of the lights of Ft. Steele.

To take comet photos you’ll need about a 10 to 20 second exposure with a SLR camera on a tripod.  (A cell phone would be a challenge.)  This magnified photo was taken on a motorized equatorial tripod so the stars don’t make streaks as the Earth rotates.

Info about Comet NEOWISE C/2020 F3

Location: It’s currently on the Northern horizon, to the left of the constellation Auriga, in Lynx, and will slowly move higher and to the left through the feet of Ursa Major (beneath the Big Dipper asterism) over the next few weeks. It went around the Sun on July 3, inside the orbit of Mercury at 0.29 AU and it’s now moving out and away.   It will be closest to Earth within 64 million miles (103 million kilometers) on July 23.

The comet’s tail: The tail generally points away from the Sun.  (It doesn’t trace out the orbital path the comet is taking as many people assume, sometimes (after perihelion) the tail can point in the opposite direction that it is going.)  The Coma: is created when the heat of the sun melts the frozen ices and dust of the nucleus, which evaporates and lifts off the surface into a globular fog around the ice and dirt. There are various ices: water ice (H2O), dry ice (CO2), carbon monoxide (CO), methane (CH4) and ammonia (NH3). Carbon monoxide ionizes the easiest.   The Ion Tail: is the thin vertical pale-blue straight line in the photo, which is made up of carbon monoxide gases ionized by the Sun’s intense UV light and is pushed directly away from the Sun by its solar wind, along the Sun’s magnetic field streamlines.  It’s a very hot plasma that glows with a pale-blue light.  Sodium Tail: not visible in the photograph, it has a red separation in the tail caused by high amounts of sodium, which also ionizes easily.   Dust Tail: The broad and fuzzy curved pale-yellow tail in the photo. These dust grains and sublimated ice vapours (like steam) are pushed away from the coma by the Sun’s slight radiation pressure.  The dust tail curves as it is pulled by gravity along the orbit behind the comet, and smaller dust grains get pushed faster by sunlight than the bigger and heavier dust grains. The vapours and dust reflect the bright sunlight.  The comet is losing hundreds of kilograms of material every minute and will get smaller as weeks go by.  It should remain visible for a few weeks.

Why the name NEOWISE C/2020 F3?  The comet was discovered by NASA’s orbiting space telescope, the Near-Earth Object Wide-field Infrared Survey Explorer, or NEOWISE, on March 27, 2020.

How big is it?  NASA says: “From its infrared signature, we can tell that it is about 5 kilometers [3 miles] across, and by combining the infrared data with visible-light images, we can tell that the comet’s nucleus is covered with sooty, dark particles left over from its formation near the birth of our solar system 4.6 billion years ago,” said Joseph Masiero, NEOWISE deputy principal investigator at NASA’s Jet Propulsion Laboratory in Southern California.

I made up this skychart in Cartes du Ciel using data from the minor planet  In the starmap you can see Ursa Major (the Big Dipper) at upper left.  The comet drifts left along the feet of Ursa Major.  It should remain visible along the Northern horizon until Jul 26.

If you get a chance, take 50mm binoculars and try to spot the pale-blue ion tail and the pale-yellow dust tail.  Otherwise it’s clearly visible by eye for a few weeks.

2018-10-5 : EMO Courtenay Fireball

A major meteor fireball was recorded from my backyard observatory known as EMO Courtenay which is part of the Sky Sentinel LLC network run by the Florida Institute of Technology.  Previously this was part of the Sandia National Labs fireball network that tracked bright flashes in our upper atmosphere for the Department of Defence in the U.S.A.  My station is:

This fireball was recorded at 11:02 p.m. on the 2nd October 2018 or UTC 10/03/2018 – 06.02.16 which is Coordinated Universal Time.  We are looking for information by observers of this event, especially possible recordings  by security cameras before the video tapes are over written.  This is so we can calculate a possible drop zone for a meteorite that may have survived to land on the ground.  Attached is a photo of the fireball recorded with my All-sky Camera.  North is at the top with East on the Left!  Please forward to radio stations on the Island.

2017-11-12 : Crawford Bay Meteorite – by Rick Nowell

Dr. Alan Hildebrand (a meteorite expert at the University of Calgary) has released photos of some small Crawford Bay meteorite fragments on CBC.  His grad student, Fabio found them.  It was a stony chondrite.  There are lots more pieces to find.  Alan says:

Finding rocks about the size of a loonie across a 20-kilometre stretch of forest is no easy task.  But this case was different because of the video footage.  “We know what orbit it fell from… and that’s only been done a couple dozen times,” Hildebrand said.  “So we now know what orbit this rock was on and that, of course, tells us a little bit about the structure of our solar system.”

Thousands of fragments, ranging from the size of a peppercorn to a bowling ball, will have hit the ground – but Hildebrand says most will be in the forest that blankets the eastern shore of Kootenay Lake.  He expects people will be finding fragments in the area for several years.

READ MORE Dr Hildebrand’s news release.

Where approximately to look?

Triangulating with these videos now locates the fireball trajectory in the sky with ~200 m uncertainty along a path 120 km long, recording its deceleration from 16 to 4 km/s.  Once the rock has slowed to <4 km/s it no longer produces light entering what is called “dark flight”.  Dr. Elizabeth Silber of Brown University calculated the surviving rocks’ paths as they fell to Earth pushed by atmospheric winds.

The predicted meteorite fall zone – what researchers call a strewn field – is  ~20 km long starting east of Crawford Bay and trending NNW across Bluebell Mountain to the Kootenay Lake shore north of Riondel.  The largest meteorites will be in the north.

Where are the meteorites?

With the prediction of where meteorites would have fallen, the U of C team headed into the search area and found the first meteorite on Oct. 29 on private fields in northeastern Crawford Bay.  Fabio Ciceri, a visiting M.Sc. student from the University of Milan made the first meteorite discovery.  Fabio says “At first I couldn’t believe it – ever since I was a child I got up with my father to see the night sky, and it was like a dream to hold a space rock in my hand.

A meteorite chunk was found by Fabio Ciceri, a masters student from the University of Milan who is studying at the University of Calgary. (Colin Hall/CBC)

The U of C team kept searching, but the approaching winter has made finding meteorites more challenging.

Dr. Hildebrand says, “We need to recover more and larger meteorites to learn what we can from this fall.  For example, with enough pieces we can tell how big the rock was when it entered the atmosphere.

Thousands of meteorites will have fallen ranging from the size of a peppercorn up to rocks weighing 5 to 10 kgs, but most will be in the forest that blankets the eastern lake shore.  To understand the challenge Hildebrand recommends standing on the main street of Crawford Bay looking north to the southern end of Bluebell Mountain, “More than one hundred meteorites are on that slope, all you have to do is find them.”.  And he expects that interested people will be finding meteorites in the forest across the strewnfield for years.

The U of C researchers also are still encouraging anyone running security or wildlife cameras in the Riondel area to check their cameras (Sept. 4 fireball start time of ~22:11:25 PDT) to see if they captured the light and shadows cast by the fireball.  This will help them check the fireball’s end location so more accurate fall locations can be predicted for the largest pieces.


2017-9-4 : Kaslo Bolide/Meteorite – by Rick Nowell

Last Sunday a huge fireball lit up Cranbrook’s whole western horizon.  From high up, first a swiftly moving ball of yellow light caught the eye.  It rapidly gained brightness, until it turned into a blue-white welding arc.  A small orange globule broke off and followed it along its wake.  Then it suddenly flared and a spray of brilliant white light flashed out and lit all the sky for miles around and casting shadows on the ground.  A large blue-white fireball zipped out of that dazzling light, with one smaller orange fireball chasing after it, slowing down and dropping over the horizon into the smoke haze until it dimmed out of sight.  Minutes later, a dull rumbling sound like thunder grumbled in the distance.

In disbelief a witness in Crawford Bay “almost ducked” as she saw it rocket close overhead, the eerie silent blue-white fireball and behind it two smaller reddish-orange balls falling away and arcing down not too far away to the North.  There was a quiet pause as she looked North wondering—what was that?  Then KRACK-WHAMMMM! recoiled to the tremendous crash of a sonic boom–so loud she felt it vibrate inside her chest, then a crackle and continuous waterfall of noise as the air tumbled back in to fill the tunnel of low pressure air the supersonic fireball had rammed through the sky.  For an endless twenty seconds this shook the house, rattling the windows, the garage doors and even the ground before dying away.  For a second she imagined it was a nuclear bomb blast.  I’m not kidding, it was that loud! she said.

Was it a small nuke?  NASA’s JPL website reported a monitoring satellite saw an air blast at 36km altitude equivalent to 0.13 kilotons of TNT.

Attachment KasloMeteor.gif above is a GIF slideshow with frames displayed every half second.  When viewed in webmail or on a web browser, it will play the animation.  Moon at lower left.  Photo credit COTR meteor cam 4 Sep 2017.

But videos show it was a meteor, a rock from outer space, with pieces falling off as it went along.

So, where did it hit the ground?  BC has a network of meteor cam stations watching to find where these hit.  The College of the Rockies has a meteor cam, and it tracked it for about ten seconds, starting from 11:11:26pm.   Six or more security cam videos saw it.  One good video from Spokane (near Gonzaga University) was used with the College video, and a photo from just South of Crawford Bay near the marina, to triangulate where the meteor hit and was able to give us a good idea.  Esko Lyytinen, a retired mathematician of the Finnish Fireball Network, kindly analyzed our video.  Summarized as follows:

The main 50kg piece would have hit about 5km East of Kaslo around: (49.8731 N,  116.8457 W).  “It flew directly over Crawford Bay but not as far as Meadow Creek”.  The main piece was last seen at 49.7603 N, 116.8350 W, still 18.9km high​.   The 100g sized fragment from the brightest flash would have hit 2.5 km South and 1km East of Riondel at around (49.7381 N, -116.8393 W).  The winds may have moved the main fragment about 750  m to the East and the 100 g fragments about 1.7 km to the East.  Thus the NE area of Crawford Bay would probably be favorable for finding fragments.  As well as from Gray Creek North to Crawford Bay along the road.   But fragments can veer in direction: after talking to witnesses, Dr. Alan Hildebrand is worried the main piece may have gone into Kootenay Lake. 

These fragmented meteors don’t make craters, craters are usually made by much larger solid nickel-iron ones.  This meteor was likely slowed down to around 200 km/h by the time it reached “dark flight”.  ​If the basket-ball sized 50kg chunk hit soft ground, it would have left a big dent about as deep as its diameter, then bounced up and landed on the surface again.   Unless it hit solid bedrock and shattered.  The smaller fragments (100g would be around golf ball sized) would have just bounced like normal rocks.

Meteorites that strike the ground are not smoking hot as depicted in Hollywood movies, so there is no need to worry about them starting a forest fire. They start off cold in outer space (about zero degrees C for meteoroids around Earth’s orbit).  Their outer surface gets white hot as it compresses the air into a plasma sheath, but this blowtorch heat is slow to penetrate the rock.  This hot layer fuses and evaporates and is blown off as droplets, dust and vapour before it can heat the inside.  So the inside remains cool during the brief 10 second fiery fall through the atmosphere. It’s rare to find a hot or warm meteorite, some have even been found with frost on them.  But the outside skin often has a one millimetre thick melted “fusion crust” with thumb-sized worn hollows.

Judging from factors like how high it fragmented, porosity, speed, cometary orbit from beyond Pluto,  Esko is betting it’s a common, stony non-metallic meteorite, a “chondrite”.  These are the most common types, they make up 86% of meteorites that are recovered.  Formed of dust, clay and small sand grains surrounding “chondrules”: small beads of silicate minerals like olivine and pyroxene.  (Olivine is a magnesium iron silicate common on Earth but quickly weathered).  May contain small amounts of magnetite, nickel-iron, or even flakes of metal.   Density about 3.5 g/cm^3 as heavy as basalt rock.  Very old, from primitive asteroids originating from the early solar system 4.5 billion years ago

Chondrite Meteorite.  Polished face showing chondrules and metal flakes.  Dark shiny fusion crust.  Photo Credit H. Raab, CC Wikipedia article.

Since it had a cometary orbit of about 50AU, Esko supposes it may even be a carbonaceous chondrite with lighter density.  That is a rare type of primitive meteorite with organic compounds such as water, amino acids and hydrocarbons.

WHAT TO LOOK FOR: Chondrites:   Look for rocks that a magnet will stick to.  The surface may have a thin grayish fusion crust (a thin melted layer one or two millimetres thick) and scattered thumb sized hollows (worn away by atmospheric friction called regmaglypts).  Although rarer meteorites like the Tagish Lake carbonaceous chondrite meteorite looked like black charcoal briquettes.


Ignore layered sedimentary rocks (shale, limestone, dolomite) since these require an ocean to form, and this wouldn’t be found on an asteroid in outer space.  Also, if it has holes or bubbles inside (like pumice) that was likely from lava flows (basalt-magma) cooled with trapped volcanic gases, on Earth (although there are rare exceptions: a large asteroid like Vesta had volcanoes).  Also, ignore rocks containing quartz or calcite, since they form in high pressure, hot watery solutions.


Magnets: Since a lot of chondrite types contain iron oxides like magnetite, and some metal rich ones contain nickel-iron chondrules, a rare-earth magnet should stick to most.


Value:  If a hiker finds a piece, it could be worth a lot of bucks per gram or it may be disappointing. Common iron meteors are only $.50/gram to $5/gram, rarer stony meteorites $2 to $20/gram, and really rare ones $100 or $1000/gram or more, depending if they have embedded gems or if they’re from Mars or the Moon. And some meteors are dense and heavy, so they go a long way. For example, back in 2000, the rare carbonaceous chondrite meteor that landed on frozen Tagish Lake on the B.C.-Yukon border brought Jim Brook, the lodge owner who found it an estimated $850,000. The University of Alberta, with Canada’s second-largest meteorite collection, bought most of the meteorite.  For sample meteorite pricing, see

The Washington University in St. Louis has a great webpage showing all sorts of meteorites at

If you do find a possible meteorite, send a photo to Dr. Hildebrand.  Note that American Meteor hunters have to report to the Canadian Customs, Canada has export restrictions on them.


Above is a flow chart guide designed by Deborah Guedes in Brazil to help identify a meteorite.  “Regmaglypts” are those worn-away thumb sized hollows in the surface.


The College meteor camera has seen large fireballs or bolides of over 100 kg that hit the ground about four times in the past six years.  The last was:
– December 20, 2014 over Canal Flats, BC hitting by Marconi Peak on White Swan Lake road. This was possibly a rare carbonaceous chondrite.
– September 26, 2011 over Banff, AB, hitting in the park.
– May 14, 2011 over Creston, BC, hitting by Duck Lake.

With shared videos from other ground stations in the BC Meteor network, like West Kelowna, Penticton, Courtney, Vancouver or Prince George, we can triangulate where these have impacted to within 2 or 3 kilometers. We then have a chance to find these rare meteorites and to find out what they contain.

College of the Rockies also belongs to the Sandia National Laboratory North American meteor network, and we upload videos of fireballs to there.”​

2017-9-4 : Kelowna Meteor – by Rick Nowell


The Cranbrook College of the Rockies meteor camera tracked last night’s fireball high over Nelson and Kootenay Lake.

Allsky video

It lasted for about ten seconds, from 05:11:26 until 05:11:37 UT.  For a brightness comparison, note the full Moon in the lower left part of the video is totally out shone by the fireball when it flares.  There is no sign of the fireball breaking up and exploding.

This video movie m20170905_051126_000.mp4, is taken with a fisheye lens that sees all the sky.  North is directly up, East to the left, West to the right, and South below.

There is also video there ( from my dash cam showing the fireball flash as seen from Cranbrook,BC. (showing only the flash, which is not as spectacular, lighting up the smoke haze).

Attached find a google map of the Kaslo, Meadow Creek, BC area.


The American Meteor Society estimates it terminated over Meadow Creek, BC.  (Meadow Creek is 30km North of Kaslo along Kootenay Lake, or about 70km North of Nelson)

More than 90 fireball reports from 6 states (CA and USA)
The AMS has received over 90 reports so far about of a fireball event seen above the state of British Columbia (Canada) on September 4th, 2017 around 10:14pm PDT (September 5th, 2017 ~ 05:14 Universal Time). The fireball was seen primarily from British Columbia but was also seen from Alberta and Saskatchewan as well as from Washington, Idaho and Montana. According to our latest estimated trajectory, the fireball traveled in a southeast to northwest direction entering the atmosphere near the small city of Boswell and terminating near Meadow Creek, British Columbia.

Excerpt from

The American Meteor Society site has reports from Bowen Island BC, Spokane Washington, Calgary Alberta, Claresholm, Alberta,  Vanscoy Saskatchewan, Post Falls Idaho, Creston BC, Nelson BC, Troy Montana etc.



I caught the fireball flash on my dash cam in Cranbrook at 11:11pm MDT.  Here’s a couple of frames taken from Cranbrook by King Street, looking West, before and after.  You can see the “CRANBROOK” sign lit up by the flash on the left.  I didn’t hear any thunder in Cranbrook.  Looks like it fell around Creston or Nelson.  People report hearing a sonic boom in Creston, and it rattled the windows in Nelson and Riondel.


(Note my dashcam clock is on Pacific time, says 22:10; which is 23:11 MDT, since it’s a minute slow).  So UT that would be Sep 5 at 05:11.



Susan from Riondel, BC mentioned “There was a tremendous flash, an bright orange and yellow ball, then about 30 seconds later a continuous loud rumbling noise.  The sound lasted a long time, and the ground shook.”  For a second she thought it might be the North Koreans sending an atomic bomb, it was that loud.

2017-9-4 : Bright flash due east of Kelowna BC

Latest News

Jeff Swayze

At approximately 10:15 PM pacific time I witnessed a bright flash due east of kelowna BC. I assume it was dry lightning, so I posted on facebook if anyone in my area had witnessed the flash. A local friend reported a similar post from one of their friends in Nelson BC at the same moment. I then assumed it could only be a meteor impact with the ionosphere for such a bright flash to occur and not repeat as with dry lightning. I assume more reports will follow.

Hi just found your website after seeing the whole sky light up south to north over Nelson BC and then 3 min later heard a huge explosion and felt my house rumble!!! It is a smokey but clear night. Wondering if you have any info about this? Craziest thing I’ve seen and felt!!! Cheers, let me know.



Kevin Skrepnek @KevinSkrepnek

Well, that was different: while sitting on a patio in #NelsonBC the entire sky lit up and a meteorite came down. Huge boom about 1m later.

I seen the meteorite in Calgary at 11:20 p.m. last night. It happened so fast that I could not get a picture of it.

2017-9-1: Asteroid 3122 Florence

Sky and Telescope has prepared four detailed charts to help observers locate 3122 Florence this week. Two of these show the asteroid’s general motion northward among the constellations. Two more show small areas of sky, plotting all stars brighter than magnitude 9.5, for North American observers on the evenings of August 29-31 and September 1-3. Note that the detailed charts are labeled for Universal Time (GMT), and you’ll have to apply a time-zone correction for your location (for example, 0h UT on August 31st corresponds to 8 pm EDT on August 30th).

During its visit, Florence will be traveling roughly south to north, crossing through the constellations Capricornus, Aquarius, Delphinus, Vulpecula, and Cygnus. An especially good opportunity occurs at about 8 pm Eastern Daylight Time on Saturday evening, September 2nd, when the asteroid crosses the quartet of 4th-magnitude stars that mark the head of Delphinus, the Dolphin. It will be gliding northward by a little less than the full Moon’s diameter each hour, motion that should be obvious by watching the asteroid’s starlike pinpoint through a telescope for just a few minutes.

Florence appears this bright, despite being far away, both because it’s among the largest near-Earth asteroids (2.7 miles across) and it has a fairly bright surface that reflects more than 20% of the sunlight that strikes it. (For comparison, the Moon’s average reflectivity is just 12%.) Although it rotates in just 2.4 hours, this asteroid must be nearly spherical because its brightness varies by no more than about 11% – too small a change to pick up by eye.

2017-8-21: Solar eclipse of Monday, Aug 21, 2017

SOLAR ECLIPSE TIME max lasting for about 2min over Vancouver, to 2min 17sec as you go to Eastern BC.

Here are times for cities across BC and Alberta. There are four numbers: the local times for the start, maximum and end, and the maximum fraction of the solar diameter covered: Victoria (09:08, 10:20, 11:37, 91%), Vancouver (09:10, 10:21, 11:37, 88%), Penticton (09:13, 10:25, 11:42, 87%), Cranbrook (10:16, 11:30, 12:48, 85%), Calgary (10:20, 11:33, 12:50, 81%), Edmonton (10:24, 11:35, 12:49, 75%).


TELESCOPE: if you setup a telescope (with a solar filter and video camera) the Sun should be seen safely on a video display.  We may see sunspots at the centre of the disc, even though the Sun is nearing sunspot minimum.

SPEED OF THE MOON’S SHADOW:  If it’s hazy with forest fire smoke, try going 7000 feet up a mountain to get clearer views.  From a mountain top, I wonder if I’ll be able to see the shadow of the Moon sweeping in from the West?  Over Eastern BC, It’s approaching at around 3,000 km/h; or 0.833 km/s.  That’s 2.5x the speed of sound, so a military jet could keep up with it, but a car can’t.  The totality shadow will be about 109km wide, and take just over 2 minutes to pass.  Source:

PATH OF TOTALITY: The Map of totality below shows you’ll have to go 500 km South of the US border to Salem, Oregon or to Idaho Falls in Idaho to get the full effect.

Map by Xavier Jubier.  http:\\

ECLIPSE GLASSES:  So, where to get adequate eyewear, sunglasses won’t do!  You can send away for cardboard eclipse glasses (mine haven’t arrived yet), but be sure they are very dark, like shade 14.  Try getting some welders replacement lenses; again, shade 14 is safest.   They are rectangular glass plates, about 4” x3” x2”.  They should be available locally at Air Liquide, or Acklands, or other welders supply place (unless they are already all sold out).
EYESIGHT WARNING: When you look at the Sun, the lens in your eyeball acts as a burning glass, and the target is the back of your eye, where imaging happens. You can also damage the protein jelly, or “aqueous humour” that fills your eyeball. The damage can be permanent. Staring at the Sun using a telesc​ope or binoculars that have not been modified for solar observing could likewise lead to permanent damage. A pair of 10×50 binoculars (10 times magnification, 50mm objective lenses), will collect between 50 and 100 times the amount of light and heat that your eye lens will collect. Permanent damage will be near instantaneous. There is specialist hardware that can be used with telescopes and binoculars that make them usable for safe solar observing. However, unless you are completely familiar with these devices and how to use them… DON’T. If you are not an expert then go find one.”  Quote from Ken Tapping, astronomer at Penticton, BC.

SOLAR PROJECTION: (adults only please) using a spotting scope or binoculars (or a magnifying glass).  Set it up on a tripod, and focus the telescope at infinity (a mountain first).  Then hold a white square of cardboard about a foot away from the eyepiece, or against a white wall (some telescopes come with a little arm and clip for this purpose).  The cardboard should be in a shadowed area.  Be careful not to look through the eyepiece of the scope (or the finderscope!)–just look at the shadow of the scope on the ground to point it at the Sun.  Centre the image of the Sun on the white card.  Move the cardboard close for a smaller/brighter image; and further away for a bigger/dimmer image. That way you get enough magnification to see sunspots too. (Galileo pioneered this projection technique back in 1612.  He didn’t go blind until he was 72, and that was from cataracts.)

FIRE AND BLINDING DANGER: Don’t hold the cardboard too close or you’ll burn a hole through it.  Don’t try to look through the eyepiece,  or you’ll burn a hole in your eye’s retina.  Don’t goof-up or you’re permanently blind.  Watch out for kids around you.  Don’t leave unattended.  Don’t burn your finger or start a fire!  (That said, I did this in grade 11 astronomy class and nobody had any trouble.)
