Strange light in Eastern European Airspace
Yesterday around 1920 UTC we were cruising in Croatian Airspace heading northwest.
Suddenly we noticed a strange light in front of us! I would say 1/10 of the sky was illuminated by this light! It was a huge light circle with a bright spot in the middle!
From our position it was moving from West to East and dissapeard after 5 minutes!
A lot of talking was going on, on all frequencies but nobody had an explanation for this event!
Someone here, who noticed this as well and could tell me what that was?
