Surge prominence 09 Feb 2023 UPDATE: full disc 10 Feb 2023

My new blocking filter finally came back from Lunt (cost me arm and a leg in shipping to and from the USA), so I braved the cold to test it today. Looks good on full disk so far, as I did not have to massively pull the black point in order to cull one side, but I reserve my judgment. It was fairly cold, sub zero, I heated BF with a dew strip but probably did not manage to pull another full disk shot after the surge prominence as the features went bland (I suspect, because of the BF cooldown). It was good while it lasted.
I first saw it visually, it was incredibly quick and by the time I put camera in it started to dissipate, all in all say 5-7 minutes before the quietness of that full disk and the other two shots.
My processing is incredibly rusty, had to re-watch Marty's tutorials and feel as if I have never processed a h-alpha photo.  So this was a very quick job...super busy at the moment.

Another wow!

What is Sol going to be doing in another year or so as it gets to solar max?

Updated...finally properly heated my blocking filter and here are the results, even at low altitude (18 degrees in the afternoon). Nine active regions going on...

Could have probably dropped magnification down, but now it is too late.

One more...two limb proms, rather large...

I saw these using my experimental 35mm DS  Ha telescope.  Unfortunately by the time I was able to travel to my 150mm Ha telescope, not only had the surge subsided but also the clouds had arrived.    ☹️
