My first Hα animation with D = 200 mm (and a flare)

Post by GreatAttractor »

On Sunday the seeing was finally good enough to utilize my RC8 + LS50THa + Aried tri-band ERF setup.

One of the best videos yielded this image of AR 2822 (check out this thread if you'd like to play with the raw stack):

I continued recording for some time, even though the seeing was variable and a high thin cloud was passing. I saw a few bright points appear, but had no way of knowing it would be a nice C4.0-class flare, until I put together an animation:

Beside the "igniting grass", note how there's a brightening in the billowing "smoke", right before a thin stream gets sucked back in to the smaller sunspot.

I'm really satisfied; even despite the so-so seeing this tiny thing looks very interesting. Can't wait for an M-class like the one I caught with 90 mm – it would fill the whole FOV with twisting and churning plasma!

I also recorded a CaK animation (Lunt CaK module, 90 mm refractor, PowerMate 2.5x), much better seeing than during the previous attempt, with consistently good resulting frames, but nothing happened there at all:

You captured some amazing dynamics from this activity region.
Beautiful to watch.
Cheers.

I caught this flare visually Sunday using my SMII60. I did not get a view like this though. That's an awesome animation at a considerable magnification.

Thanks, everyone. Too bad seeing was deteriorating and clouds started rolling in – NOAA says 50 minutes later there was another flare in this AR, also C-class, but over twice as powerful.
