looked like a partial prominence with an extremely bright ball at one edge

several minutes later it had faded and move upwards quite far

 

edit:

it was on the opposite side as the image by MalVeauX today

correction, same side as his animation i think

I wonder if it's AR2738's death throes, belching out filaments and surge proms. I watched it do that this morning around 10:30am too. And all day on GONG there's been a new surge prom every little bit that appears, lifts off, and goes away. It's done it a few times today.

 

Very best,

I saw a prom lift off at around 15:33MST, it evolved into a rather bright ball about 15:35 or 15:36 and then faded out over the next couple of minutes.  It was right at the equator, so I think Marty is right and it was just AR2738 coughing up a plasmaball.

Very best,

think so, it was about 22:35 UTC, the ball looked as bright as the disk, looks like it was between frames in the video, very dynamic

Actually the pumping prominence was fortunate to happen as I was tuning a brand new daystar prominence Quark for the first time.  Way off band (far clockwise) when I first caught sight of the prominence activity - still ez to see, I swung the temp setting full cc for a better tuning start.  Adding a heavy batch of intermittent clouds to the mix, there wasn’t really anything else I could Identify.  Should have bought the chrominance version to show Ha surface texture. (Already have access to a 80mm DS Lunt though).
