ObservationYes
RemarquesThe meteor grew brighter as it descended from about 20 degrees from the zenith in an easterly direction until it was about 50 degrees from the zenith about 10 degrees east of north. It fragmented at the end when it was brightest, then faded rapidly. Two other people were with me, and were able to turn and follow my line of sight as I uttered a long Woooow. Duration was hard for me to judge it could have been as long as three seconds. I am a PhD physcicist, the other two are a physics and electronics teacher and a computer scientist, (my brother in law and his son). We had been using a 10 inch reflector telescope before seeing the fireball. It was by far the brightest I have ever seen.
Fragmentation
ObservationOui
RemarquesIt grew larger in size and fragments trailed out, then rapidly faded.
