Reports Report 2714b (Event 2714-2016)

Observer
Name John W
Experience Level 4/5
Remarks I wish the form asked earlier about constellations that it passed through or let me draw on a star chart, because I can give that information more accurately than guessing angles. I first sighted it in the lower-middle of the square of Pegasus as it emerged from behind a tree. It traveled south, passing a bit below (east of) Alpha Pegasi, the bright flash and fragmentation that I reported happened as it crossed into Aquarius, and it fizzled quite close to Sigma Aquarii.
