29 Dec 2022, Animation of Christmas tree Prom, post Flare Loop & Surge

Post by H-Alpha »

Hi all,

I hope this finds you well.

Yesterday I had a nice observation and was lucky with my animation targeted captures (despite the tuning problems).

I had them 'all in one', a Christmas Tree Prom, a past Flare Loop (which originally attracted my attention), and a Surge next to it.

However, I did not know how to present the animation. I would have spent even more time to try to invert the sun surface or the proms. I may try this later. I present you four different options and please let me know which one you prefer, if you wish.

(almost) Full frame with proper orientation

Only after uploading this post, I realized this annoying flickering on the solar surface and cannot understand to what it is due... Chmmmm... I had it in the past in animations much longer in less intensity. I made a batch process of frames, so I cannot really explain why it is so important. Possibly very thin clouds? It could be.

Best wishes,
Alexandros

Wonderful catch Alexandros! I'm torn between the 2nd and 3rd one. I like the details that show in the 2nd one since you can see the involvement of the surface but of course there is less flashing in the 3rd since the disk is blacked out which masks the effect of high clouds that definitely causes the flickering of the disk. I did run that 2nd animation through Pixinsight's Batch Linear Fit which can help when you have a variation in the histogram between frames in your animations.

Thanks a lot Warren!

Fantastic improvement in Pixinsight! I had downloaded it last summer while learning to process Deep Sky photos and was quite difficult. Then I stopped DS due to planets apparition and did not buy it. I will at a certain moment. When you learn it it it can do fantastic things apparently. I am curious, how long did it take for you to correct the flickering in the animation?

Best wishes,
Alexandros

Alexandros,
I observed this prom and the surge area north of it visually yesterday though it looked a bit different visually at the time I observed. The prom itself was very easy with nice detail and the surge area north of it was easily seen but I never saw any of the plasma streams between them. Either I observed before or too far after the flare that caused them or they were too faint for me to pick up in double-stack.

These are really nice animations. They show so much more going on than a visual view or still image can show. Which way does the plasma flow in the streamers go? Away from the big Christmas tree prom or towards it? They go away in the first four and towards in the last one edited by Warren.

Also look at the movement of the spicules/plasma around the big spot of AR13176 in your first image. I noticed a defined area around that spot on the 27th. Fascinating... 🧐

James

P.S. The flicker is a minor thing in such a good set of animations.

I had a feeling that you would write that you observed all this visually, and here you are! ;-)

I also had not observed the plasma until I processed the first test capture! It was very faint apparently.

Best wishes for a Happy New Year!

Alexandros,
With you being in Italy you probably imaged the area several hours before my visual view of it. While one can observe change real-time visually the sped-up time in animations make it so much more obvious!!

I see and you animate!!

Happy New Year to You and Your Family too!!

It takes very little time at all. I first opened your animation in Photoshop and then exported the layers as files into a folder. Then in Pixinsight I open up Scripts/Batch Processing/Batch Linear Fit. I select all the images in the folder I moved the files to, then I select the one image I want to match the histograms to. In this case I picked one of the images that looked the best. You then make a folder for the files, change the output so the files are saved as TIF's and hit run. The adjusted files can then be made back into a GIF or other media of your choice. Here is a quick tutorial I put together for doing this: https://youtu.be/IKZmipr0mYs

Fabulous animations, I like number 1 and 2 best :bow :hamster: :movie but yes like James said, I am presuming Warren's is reversed?

Happy New Year!

Yeah, I forgot to reverse the frames which Photoshop does for some reason! I replaced the file with the correct sorting of the frames

Very good tutorial. I downloaded it in my folder of very useful ones. I am tempted to buy PixInsight only for this, although as I wrote already I had the trial version to work some deep sky photos.

Happy New Year!
