Reports Report 3992m (Event 3992-2017)

Name John C
Experience Level 4/5
Remarks Five to 10 seconds duration, very long-lived compared to other meteors and fireballs I've seen. Very slow angular velocity. Had plenty of time to point it out to my wife who watched much of its trajectory. We were in our car next to Costco building driving due north. Saw it off to left a little, starting about at bottom edge of Big Dipper, down and to the right fairly steeply. Faded out just a little above horizon. 7:07 pm was accurately noted right away.

Remarks Very slow fireball from our angle, first 2 or 3 full seconds was bright white ball, then flared up slightly, started crumbling for 2 or 3 full seconds, then faded out to dull orange over a full second. Plenty of time to point it out to my wife who watched 3/4 of the flight.
