October 30, 2020 bombs away?

[Astrophil]

Hi All,
Here is an off band animation of AR2778 and AR2779 attempting to show Ellerman bombs. Seeing deteriorated rapidly over the 40 min. capture. The etalon temperature was set to 44.7 ºC resulting in a center wavelength of about 1.4 Angstroms into the blue. Truthfully, I have no idea what the best etalon temperature should be.
Also shown is an image on band.

Phil:
Super shot and animation.
Best regards,

I wanna do some more observations of Ellerman bombs. They are a true challenge visually. You " bombed away " excellently with these images and captured them superbly.

[Rusted]

Superb animation and image.

The fleeting filaments give the animation an almost organic, "pond life" appearance.

[Carbon60]

Excellent, Phil.

Lots going on there, even away from the main action within the spicule field. Those ‘mini’ explosions within the ARs themselves are mesmerising. Their apparent small size relative to the sunspots belies their true explosive power.

Very nicely done.

These are stunners Phil!

[ffellah]

Super shots, Phil ! Love both.

Excellent image and animation Phil...well done

Fascinating animation!

I think that is pretty much a first Phil

A lot are static bright points indicating flux tube foot points but there are some particular bright flashes of Elleman bombs. Particularly at 12 o'clock on the lower left spot and also at 2 o'clock on this same group where the black material is ejected. Well done sir, a job well done!

Thank you all for the comments. One additional bit of info pertaining to the animation, 1 frame per minute recorded 10 frames per second video playback. (1 sec. = 10 min.)

Alexandra, thank you for the analysis. I think I learned something.

Hi Phil,

Excellent.

[LeoD]

thanks, Phil, very interesting off band animation! Perfectly processed.
I made shots in the blue wing with SM90, but, definitely, I have to try animation too.

Hi Phil, that's a great animation and explanation of your imaging process, thanks for sharing this valuable piece of information with us.

It made an awesome well deserved SPOD too!!

Hello Phil
Excellent image and great off-band-animation.

Great, great work Phil off-band images reveal many interesting details, they are usual for professionals.

Waiting to try something like that with my equipment too.

[Lowjiber]

Great work, Phil. The animation is stunning. Thanks for sharing your work.

Thanks again for the kind remarks. Looking further into Ellerman bombs, one study suggests maximum visibility in Ha would be in the wings at plus or minus 0.8 Å. If the occasion arises I will try again in that wavelength. Unfortunately, the temperature controller I have will not heat the etalon enough for a red wing test so only blue wing for me.
I borrowed a diagram showing where EBs hide. (Solarwiki)

Phil...great addition with the graphic of the structures involved!

Yes, It helps us understand the processes that lead to the formation of Ellerman Bombs. Thanks Phil!
