Reports Report 2600b (Event 2600-2016)

Observer
Name Robert R
Experience Level 4/5
Remarks Last question, better answer. I teach celestial navigation professionally, and my academic background is in astronomy, but I don't have a specific interest in meteorites. This object appeared very similar to a bright green pyrotechnic flare. I actually at first thought it might have been a firework nearby, but there were no people or boats to have set one off there, and there was no sound, and no other incidents.
