Reports Report 1684g (Event 1684-2017)

Observer
Name Gail M
Experience Level 3/5
Remarks There were three of us (out counting night birds in the park) - we all observed the fireball, even though one of our party was separated from us about 100m away. I was focusing on a calling bird in the woods ahead of us, when I noticed out of the corner of my eye a bright light above me. My husband looked up at the same time. For a fraction of a second I thought it was a low flying helicopter, albeit a silent one, but immediately realized it was a fireball. It passed overhead, with at least two episodes of fragmentation, before falling below the tree line. However it was so bright that it could still be easily observed through the thin foliage. From directly overhead -when first observed - I would estimate it arced though about 30 degrees of the sky. We did speculate that it might have been a failing satellite, not a meteor. ( I should add that I have my graduate degree from Dept. Of Earth & Planetary Sciences of Johns Hopkins, and was teaching assistant for course in astronomy of solar system, so not a totally naive observer. )
