Surge Prominence at SE, Animation with bad seeing

Post by H-Alpha »

Hi all,

Today the seeing was much worst apart a few minutes in the beginning of my session (no Jetstream, excellent forecast, but ...40 degress Celcius). Therefore, I decided not to capture an animation and make some visuals and a few trials with a Bad quality old Celestron Barlow 2x.

Nevertheless, before stopping all imaging effort and while wondering around the limb, I observed a bright small feature at SE and thought to see how it will evolve through an animation of 1h. The image is very bad and the Barlow gives Newtonian rings, but I have not observed something like this before, so wanted to ask you if this is a mini flare, a special prom (much brighter than commonly), or something else.

I start with a photo of the NE proms (Lunt130MT, ASI290MM)

The same proms with the bad Celestron Barlow 2x and Newtonian rings despite the flat that I made! Although I am new to flats and may have done something wrong... With this opportunity which amplifier 2x would you propose as very good quality for solar?

And finally THE BRIGHT ERUPTIVE FEATURE that is of unknown type to me. The animation is of 63 minutes, 66 frames. We can see some material being ejected violently towards the outer space at a certain moment, and then suddenly an ejected 'fireball' accelerates a lot!

All comments regarding both Amplifiers (Barlows etc.) and the unknown to me bright eruptive 'thing', are very welcome!

Best wishes,
Alexandros

It looks like a surge prominence. They are often flare related. There is certainly some activity going on below it.

I agree too :)
I find this little chart here very useful, you need to scroll down and look for Solar prominence classification https://www.prairieastronomyclub.org/ob ... n-h-alpha/

Great animation :movie

Just out of interest you said you would be doing research at sea in August, are you a marine biologist? Pedro Re is also a marine biologist

This prominence is believed to from AR2835 which currently has 3-spots in a smaller region than the large AR just to the south of it.

The attached image refers.

Thank you all, James, Stuart, Alexandra, Terry, Franco.

A Surge Prominence! New to me! Thanks guys and girls. ;-)

@ Terry: This very promising! Let's see how it will evolve our new friend the AR12835.

Alexandra this chart is indeed very good and useful! Many thanks! You gave me lot of homework (for cloudy days ;-) )

And yes, you guessed right! I am a marine biologist like Pedro. We had exchanged a PM on this early this year.
I started by studying the ecology of benthic animals (whose life depends on the see bed), but then the 25 years together with our team we study and try to conserve whales and dolphins in Greece, the Mediterranean and globally. You might wish to have a look on some amazing short videos that we produced recently on sperm whales and other cetaceans through drone filming:
