Hey all,
Woke up to a mostly clear sky, but the seeing was not great, so I had to keep the scale down. But that's ok, I still managed some decent data. I had to grab a lot of frames to even get a few to stack in the poor seeing. All of these were done with maximum gamma, 5ms time and only enough gain to get to around 80% histogram fill. I grabbed around 6000 frames on each feature to try and get somewhere around 31 to 101 to stack that are decent. I used the 152mm F8 refractor with a 0.5x focal reducer and the Quark for most of these. The convection cells were at full scale with the same refractor and a 3x barlow with a near UV filter. The ST80, masked to 60mm, with the Quark was used to do a mosaic of the disc.
Celestron 152mm F8 refractor + Quark + 0.5x Focal Reducer + ASI174MM (all HA)
Celestron 152mm F8 refractor + 370~395nm pass filter + 3x barlow + ASI174MM (convection cells)
Orion ST80 80mm F5 refractor (masked to 60mm) + Quark + ASI174MM (HA disc mosaic)

New sunspot, 2719, really interesting on the limb with some flaring:

Hi Marty,
Great images. Is 2719 official already ? I just opened Spaceweather.com and there it is not listed ...

Probably not official; I haven't seen anything truly designate it yet. I may have jumped the gun, so to speak. But it has a visible umbra, unlike 2718 which has decayed already. This new AR is still active, flaring a bit, hopefully it will be designated, I don't think it's a previous AR nor relative to the AR2718, so hopefully it will receive designation!
Very best,

Very best,
Congratulations. Sunspot 2719 is alive. Just checked Spaceweather.com

Woo! Official! And it has several umbra, unlike 2718 did, this is a more interesting spot so far.
Very best,
