Need help to understand what i captured on video
Good evening everyone,

Last sunday (22nd of december) around 12:20PM, I went with my father for a trip by the coast to look at the massive waves.

I review the footage when we arrived home and to my surprise, from 10sec up to 13/14sec you can see some sort of a ball in the sky going into the atlantic ocean. Maybe its my brain who fucks up with me based on what’s going on in the US. But i though I would share it with you so you could tell me what you think. I thought about a bird first but it seems quite high and then take a fast deep dive so I really don’t know.

Thanks a lot for your help.
