Today was another clear day for my solar photo endeavors. Rather than make 5-minute AVIs, today I tried making 30-second AVIs and stacking the best 20% of the frames. My intention was to make such an AVI every minute for 10 minutes in the hope of then making a stacked image of each and combining them to make a time-lapse movie of the prominences. I had partial success, but my efforts are not yet ready for prime time. 🙂
The H-alpha image below doesn’t show as much detail as my 5-minute stacks do because it is a 30-second stack. The most noteworthy change from yesterday’s image is that this one has the correct orientation; yesterday’s image was rotated 90-degrees counterclockwise. Sigh. There is a dramatic loop prominence along the northeast limb today.
The active regions that we saw in yesterday’s sunspot image are stable and relatively quiet – no big flares in the last 24 hours.
A highlight of the NE loop prominence is shown below.
