(meteorobs) Fireball?

[Nikola Bilišskov]

Dear members!
One friend sent me today a photograph showing thuderstorm clouds, and 
one green stripe. She tell that she observed it also by eye, and it 
fragmented into two pieces.
Although I'm pretty sure that it is not of meteor origin, than some kind 
of thunder, it may be also a reflection of a big fireball.
So let me inform if anybody, from countries around Croatia, saw a 
fireball in the night August 20/21, on 23:17 h CET).
