Reports Report 3371aq (Event 3371-2017)

Name Helmut B
Experience Level 3/5
Remarks Moving west to east, likely something falling out of orbit? It had a big shock semi circle around it. Never seen anything like it. Turns out it was most likely an Atlas V rocket launch out of vandenberg. The crescent shape around the object was likely the expanded rocket exhaust as it flew in a vacuum. I should have known this last night given I am a rocket propulsion Engineer!
