These are 2 subs from last night, on the left an ordinary one that looks just like the others. On the right a single one with these extra features in it. They are 5 minutes subs. It was windy last night and I had to discard a few because of double stars but this one on the right is the only one like that. It looks good except for the extra features in it. I am mostly curious about the 2 round spots. They look like stars bu they’re obviously not. Anyone has any idea what they are ? There is no sign of them in the previous and next subs. I can’t figure out what could have this almost perfectly round shape and appear and disappear within 5 minutes.

What are these ?
Engaging
No idea what it could be but I also noticed there were a couple of streaks either side of the bottom circled ‘star’. Potentially some sort of weird reflection?

My guess would be something that flew through your frame and either flashing or rotating, most likely a satellite.
Hi Eric,
This is the strobe light on the underside of an airplane. The strobe very briefly illuminates the engines which is what you can see off to the sides of the dot. Living near an airport I would get these all the time. In your case, the wingtip lights weren’t on, so it is less obvious at first glance.
Well written Helpful Respectful Concise Engaging Supportive

That makes sense. Thank you
