I created an account so I could respond. But now I'm seeing it's from 2013 😔 I hope it's still active. I have been trying to figure out what this tiny little green flash is in the sky for years I've seen it multiple times every once in a while I've had a friend see it as well and just about 2 weeks ago my mother saw it with me too and I've been in two different locations when I've seen this and I have not for the life of me been able to figure out from anybody what it could possibly be. but it is a tiny neon green flash almost like a very very far away camera flash itty bitty very isolated. And only once have I ever observed it Flash and then flash again a few seconds later but in a different spot and then again a few seconds later and in a different spot. I'm thankful that I have witnesses and in different types of people but still just no answers.
