I was just out for a quick peek at the Sun with my PST at 10:30. I saw a (prom or loop?)that was lit up more than the others around the Suns disc. It also appeared to be not connected at all to the disc, just floating out there. It was just off the limb from where the big sunspot it. It looked like the letter "A". I grabbed a couple of other stronger EP's to get a closer look, but did not like loosing some of the detail I had in my 12-13mm EP's. Well here it is 10 min. later and that wispy prom has changed shape and intensity. I think this is my first observation of something actually moving in such a short time.

Anyone else notice this today?

First moving prom has got to be the coolest thing to see. I did not see today's, I caught mine last summer, stoked for hours after. If you have the helioviewer on your computer, you could run that and get some pictures from SDO. Was it hard to pull your eye away to change eyepieces?

I probably didn't realize I was watching it blow at first. It was illuminated much different and brighter then the others around the limb and then I figured it was detached from the disc. At first it looked just like the letter A and started to change shape as I was changing EP's. Backed off the magnification and just had a grin on my face:)

I did take a quick look at that helioviewer you mentioned and did see the Prom at 10:30. It was right on top of the sun in that image. I'll have to figure out how to use that viewer.

Ha observing is a lot of fun so far, but not looking forward to the summer heat when it starts.
