Hey everyone, hope you're all smiling :D

Been a busy week, and the weather has not helped. From Monday to Wednesday there was a lot of rain, mild temps at 5-10C (40-50F) and more fog than I thought possible. Made driving on my mostly rural route a fun time. Wednesday night the temperature dropped, and Thursday we got 10cm's (4 inches) of snow. Not a big deal, but with the high winds it didn't help. Driving down a road next to a treeline; clear road. Pass by a farmers field that's to the north, and you hit almost a foot of snow that's piled up on the road with the wind blowing the snow south. I called it a day at noon. Played catch up Friday in the now -25C (-13F) cold, got in at 5, had dinner and went downstairs and fell asleep to a documentary about the SLS. Today I dragged my sorry carcass out of bed at 11AM. Memories of being a teenager...

I actually felt rested for the first time in a bit. A little too much white-knuckle driving this week. The girls had been up for a few hours and were watching Hell's Kitchen.
I had some coffee and volunteered to make french (egg?) toast as only I can. I'm not chef Ramsay, but it would probably pass his taste test. Everything after that would be an epic fail!

It was a nice day, though still cold. Sarah and I went to get some beer and steaks for a BBQ. There's something about a steak done on a charcoal BBQ in temps below freezing that lends a certain taste to it.

Before I lit the BBQ, I checked the SOHO website and saw there was a fair amount of activity on ol' Sol. Such a clear day at -20C (-4F); I thought why not? It's only cold out; not a bit of wind.
The Sun beaming down on me with all of its Vitamin D made it feel a bit warmer than it was :lol:

I got my usual arsenal; C80-HD, Baader 5.0 film, Solar Continuum and UV/IR cut filters and Canon EOS 550D on my CG4. I let all that sit outside for a half hour to acclimatise, then I took 130 shots at ISO 800 and 1/200th sec exp. Aligned those in PIPP, stacked the best 25% in AS3, mildly processed that result in ImPPG, and scaled the final image in PSP9 with the planets to scale.

AR3190 is a bit bigger than Uranus or Neptune (~50,000 KM's or ~30,000 miles in diameter); I placed Uranus for scale next to the spot:

Solar cycle 25 seems to be coming along nicely since late 2021; I started taking pics with this setup in 2016. Solar cycle 24; what a dud. However, It is fun to look to look back through the activity progression of our star since then!


One more beer, and I'm off to bed. The steaks were great BTW :D Have a great day/night all!

Great report Mark!

Some serious activity on Sol for sure!

The steaks, beer and family sound great. Especially right now! I'm up at the pc during one of my "wake breaks" while imaging. A nice 3C here on a clear, cool night.

Thanks for your post and nice captures. You are a seasoned "Solar Head" now and your images/annotations show it. Take care buddy!

Hi Mark. A very nice solar image in white light using your trusty C80-HD telescope. As always, I enjoyed your annotated version and the enlarged AR3190 capture was an extra treat. Thanks for sharing the view with us Mark and keep up the great work.

Nice to know that there's a lot going on in white light as well as narrowband.

I really like these shots.
