Hi Jean,

You are the solar Monster! Absolutely fantastic images with such aperture and for a colder season.

Keep them coming.

I watch your YT videos regularly. You set an incredibly high standard.
Only yesterday, I was wondering whether you were still active.

Hi :)
Thank you all for your friendly comments!!!!

I just added a version of AR2786 on the limb in close-up

with my work , I unfortunately have less and less time to devote to the Sun, regretfully!!!

with the new cycle starting , I hope to do some more solar, when I have time

I look forward to retirement!! :)
