RemarksI was standing in the middle of a park, away from street lights. The fireball was white in color, almost like burning sodium. It looked round. There was a trail flowing behind it, fanning it out. I happened to be looking up at the stars when I noticed the fireball directly overhead. It went for about 2 seconds in a straight line towards the northwest, then seemed to explode, but there was no sound. The most interesting thing to me was that a someone else came up to me about a minute later, and asked me if I had seen the trees in the park light up, like it was daylight for a second. The bystander did not see the fireball itself.
Terminal flash
ObservationYes
RemarksSee previous note. Why would the landscape suddenly light up when the fireball exploded? Does that mean it was very close?
Fragmentation
ObservationUnknown
