Observer
NameRussell K
Experience Level3/5
RemarksThe time I wrote 21:00 may not be exact but very close. The light appeared a couple of seconds before we saw the fireball. It came from behind us as we were walking north. My wife thinks the light was more yellow than white. The sonic book occurred 2 to 3 minutes after we saw the fireball.
