Full disk H-alpha animations on 3rd and 4th of July 2021

[cmas]

I've been testing the idea of doing some longer animations using full disk H-alpha equipment and here are my latest results. The circle in the upper left corner of the animations show roughly the size of the Earth compared to the Sun.

I did some not very well planned testing on 3rd and there was some flare erupting (see around 2 o'clock in the animations) so I ended up recording 16 videos of 4000 frames in 50 minutes. Today I recorded my data over 54 minutes (41 videos, 3000 frames each). And today I used constant intervals meaning that I recorded 3000 frames (around 20 sec) and then waited 60 seconds, then another round and so on. I started with 25 videos but I took more on the fly as I had more time than initially planned. Based on my laptop battery I could have taken around 45 videos before draining the battery and I had a total of 178 GB of data (I have around 190 GB of empty space on my laptop ssd reserved for imaging. So I could have taken a few more videos, but maybe next time. Today's session also showed me well that imaging with an alt-az is problematic with such a tight fit to the sensor as I am using as there really is not that much empty space available around the disk after cropping to fit all frames.

So, let's start with 3rd of July (color and bw versions):




And there was also quite a bit happening today also (maybe 4th of July fireworks for the US solar observers? ), again color and bw versions:

Hi

Very good.

I got the first two to show movement here. Clicked on and went to Flikr and back. Did not work for last 2.

Thanks. Andrew.

Excellent FD animations Tommi!
Thanks for sharing.
Best wishes,

Sorry to hear that. They seem to be working for me using both mobile and PC. They can take some time to load as the last two animations are around 50 MB each.

They all 4 work for me. Very nice! A flare in the NW is easily seen.

Hi.

I will give them more time then.

Well done James.

These are absolutely superb, beautiful processing and presentation too

Is that the X-class flare in the first?
In the second that region is still bubbling away with a beautiful prominence giving away its presence.

Thank you!

About the flare in the first: I'm not sure about the class. I'd need to check the timing against some database. But I do know the imaging times so this could be checked. First animation was taken between 08:43:02 and 09:33:43 Finnish time (UTC+3) and the second between 09:33:43 - 10:27:42 Finnish time (UTC+3). The second animation indeed reveals the wrath of the AR

I had some issues in the animation as ImPPG, PIPP or Photoshop cannot align my frames so that limb movement would be visible. There's not much of that anyways, but I think my issue arises from alt-az mount which would require both translation and rotation and focus on the limb while aligning.

I also wish that I'd have Valery's new quark with that really good and flat field, but you can't have it all! Besides that, I think I'll just continue imaging
