Observer
NameRob N
Experience Level1/5
RemarksIt would be great if someone was able to get back to me. I've never seen anything like it and thought at first it might be a firework but it was completely the wrong trajectory for a firework, and also there were no other fireworks going off that night (or noise). I'd love to find out more!
