Sun FD in H-Alpha and CaK 9th of October 2021

Post by arnedanielsen »

Dear friends,

After 10 days of clouds and lots of rain the sky finally cleared long enough to get a few FD images around noon today. I missed the solar flare from AR 2882 earlier in the day, but the region was still quite photogenic. There were also some nice prom activity.

FD image in H-Alpha using a Coronado 60mm/BF15 w/Beloptik ITF, stopped down to 50mm, Baader 35nm H-Alpha and ASI 178mm mounted on a SkyWatcher SolarQuest.

Arne!

These are beautiful! I especially like the colored CaK image. CaK always shows the plages so well! Usually better than Ha shows them and better than continuum shows their facular equivalents.

Thank you very much Ivan and James for your kind comments!

Alexandra: Will do. I'm running an all sky camera from the observatory, but nothing to bee seen yet. It looks like it's going to stay clear tonight so fingers crossed for some nice activity.

Best regards,
Arne

Thank you very much for your kind comments Leo, Brian and Mark!

The CME hit earth a bit late for Auroras to be visible from my longitude and it looks like Canada and even Northern US got more lucky.
I kept an all sky camera recording all night, but could not see anything but a faint glow in the northern horizon. Good auroras were reported from mid- and northern Norway though.

Best regards,
Arne
