I was looking at sunspots today at   https://gong2.nso.edu 
The Scope at    9 Big Bear  captured the attached image. 

 

What is the dimple below center.  ??

 

It has the appearance of a Splash from something hitting the surface and creating a wake rather than something escaping to the surface. 

I've never seen anything like it.

Thanks

My vote's for an aberration or artifact at this point. If it's a phenomenon we should know early tomorrow when the science on it comes out. It can't be a splash as we think of it because there's no surface as we normally think of it.

I agree it's likely an artifact. It's too perfect.

It appears that the "bowl" is shady on one side, pretty weird to have shade on one side and to also be on the sun.

 

I blame AI.

I’m not sure what it is, but it doesn’t appear to be a solar feature. Going back more than two weeks it stays in the exact same spot in each frame it is in and does not move with the rotation of the sun.
It does look neat though!

It's an artifact of the Big Bear camera system. None of the other seven Gong site's photos show it:

Impact crater?  Oh wait solar, not lunar.

They rarely seem to bother checking for focus or tuning at any of the GONG sites from what I see , so hardly surprising that the kit fails to get a wipe over once in a while ...

A dust artifact, or an error in the flat applied I think

A mysterious dust particle in the imaging train. Fascinating.

[gstrumol]

Definitely dust. Nothing to see here folks, move on ...

Thanks All .

I'm new to SOLAR observing.  At a recent club swap meet, I recently picked up a 80mm refractor with Orion Glass Filter,  Fine Focus Adjuster and a rail that slips into my spare SE Mount.    

Still Learning much each time out.
