Every time there is a new incident, create a new FORUM under the category “Incidents”. This is where discussion around the incident takes place.
Please capture sighting on video as quickly as you can possibly react.
- Sightings that last less than 30 seconds: the vast majority of fireballs are only visible for few seconds. Report to the American Meteor Society : http://www.amsmeteors.org/fireballs/
- Slow blinking objects or lights crossing the sky going : After checking for Venus and the ISS, report to : https://mufoncms.com/cgi-bin/report_handler.pl
A fireball is another term for a very bright meteor, generally brighter than magnitude -4, which is about the same magnitude of the planet Venus as seen in the morning or evening sky. A bolide is a special type of fireball which explodes in a bright terminal flash at its end, often with visible fragmentation.
If you happen to see one of these memorable events, we would ask that you report it here to the American Meteor Society, remembering as many details as possible. This will include things such as brightness, length across the sky, color, and duration (how long did it last), it is most helpful of the observer will mentally note the beginning and end points of the fireball with regard to background star constellations, or compass direction and angular elevation above the horizon.
Individual reports are shared with other interested organizations, and saved for statistical study purposes. Reports are also shared with the general public in the form of our Fireball Sightings Log, which allows visitors to monitor the fireball activity which is reported to us from across North America, over the course of a given year. Although the AMS does not pursue fireball reports with the intent of recovering meteorites, we do notify relevant planetary scientists when promising events occur in their local geographic areas, for them to pursue as they wish.

Dear Gerhard Drolshagen : On the Orbit of WT1190F (aka Snoopy)
Does object get captured weeks before and go into earth’s orbit, slowly losing speed and descending? OR does it come shooting directly into the earth’s atmosphere – almost perpendicular to a tangent ie pointing at the earth’s centre? This is important because if it orbits the earth one or two times as it slows down, then we might see it in the dark of the late evening where we are on West Coast of North America..
If you look at the ISS paths then focus in on the one which crosses southern India, this might indicate that SNOOPY (coming also NW-> SE) would pass over Panana, Bahamas, Northern Spain , Mediterranean and then IRAN . No luck for west coast of USA/Canada where I am.
Gerhard Drolshagen forwarded your message to me. Here is some of the info we have on WT1190F.
The object has been in Earth’s orbit at least since 2009. It has been moving in an elongated orbit with apogee at about twice the distance of the Moon, and perigee getting closer and closer to the Earth, until the upcoming re-entry. Since 2009, it has completed dozens of orbits around the Earth, and each orbit is about a month long.
The impact trajectory is not very vertical, but still much steeper than the typical re-entry of a low-orbiting satellite. It will come in with an angle of about 20° from the horizontal (=70° from vertical).
Given the fact that the orbit is so long, the geometry is totally different from a pass of the ISS. The latter orbits the Earth in about 90 minutes, while WT1190F takes weeks. So the current pass is actually the last part of the last orbit for this object.
Anyway, from a geometry point of view, it will definitely be observable from north America in the morning hours of November 12. However, it will be very faint, magnitude 19 or so, invisible by eye even with a large telescope. A CCD camera and at least a moderate-size telescope will be needed to get an image of it at that time.
Even for Europe and Northern Africa, which are the countries best-placed to observe it just hours before impact, it will only reach magnitude 15 or so, too faint for anything but images with a good telescope.
If you want to get an ephemeris for a specific site, I suggest you use this page from the Minor Planet Center: http://www.minorplanetcenter.net/iau/artsats/artsats.html. Just select WT1190F, enter the required information, and you will get your specific ephemeris based on the latest data.
Let us know if you need any additional info, and thanks for contacting us.

2015-11-13 : 10:21 PST. Splashdown was last night at 22:19 PST in SRI LANKA off coast of Matara. Was late evening on USA Westcoast Thursday. Please enjoy my Blog. This is a conversation between young post-grad scientist Subath Amaradasa of the “Near Earth Objects” Team at the University of Ruhuna, who is on ground with French scientists from European Space Agency and William Smith who is the Hoyle-Shield coordinator at Cattle Point DARK SKY Urban Star Park, Victoria, Canada.
PS There will be a post script to the Snoopy event. Snoopy is almost certainly the Apollo 10 lunar lander – aka Snoopy. Its orbit which reaches way past the moon, makes this almost certain. No wonder it burned out. Very high speed entering the upper atmosphere. Ten times the speed of the fastest bullet on earth. Being small and with no shielding, no wonder it quickly burned out. Thanks to Rick Nowell for inspiring Subath Amaradasa and his “Near Earth Object” team at the University of Ruhuna in Matara, Sri Lanka.
