Found out about this in r/aliens. Original post link👉 https://www.reddit.com/r/aliens/comments/1hgs9mu/serious_watching_the…

Some have pointed out it could be a lighthouse, others have said it could be the moon? Kinda of strange that that lights up periodically, even the beach sand looks like it's reflecting the light. Maybe there is something going on in the ocean? Could it be related to the drones? 

Any theories or explanations?
