As the sun was about to rise on September 9, 2008 an unpredicted outbreak of the September Perseid shower occurred.
Jeff, at the West Kelowna site, checked his overnight Sentinel video captures and quickly noted an unusual cluster of fireballs. Below is a composite image of of the outbreak.
Brower notified Dr. Peter Jenniskens of the large number of fireballs via e-mail. Jenniskens then sent inquiries to other observers to confirm the outbreak. Almost simultaneously reports of the outbreak started coming in on various meteor forums . As soon as Jenniskens received supporting information he issued a telegram, CBET 1501, as shown below.
