Description

Hi!
I'm watching the webcams right now and there seems to be a lot of activity. These screenshots are from just now from this feed:

Could anyone tell me what that artifact on the right side of the screen is that looks like some sort of shield? I know it's not a shield but it's the best way to describe it.

Thanks!
