METEOR? Taken by Harry Durgin on January 26, 2017 @ Hawaii island
Found this in the middle of doing an Andromeda stack. I was up around 7,000 on Mauna Loa on the Big Island of Hawaii. Didnt show up on the shot just before or after. This was at 8:06pm HST. Checked the satellite tracking websites, and didnt find a match.
