Solar Cycle Sunspot Number Progression

ChrisSmolinski:
As I am typing this, the SSN is... 12. That's it, 12.

~SIGINT~:
00:00 UTC 02 DEC 2022

The SSN is still at 12 and the Kp is at 5. This is ok for short distances but definitely not so good for any long distance work. There will be a bit of a window of opportunity between 08:00 to 11:30 UTC followed by 15:00 to 20:00 UTC. Obviously, all subject to change.

ChrisSmolinski:
The SSN is up to 49 now with a new sunspot rotating into view. A few C class flares so far.

If anyone knows of other related RSS feeds I would be interested in the links.

SSN is 93 at the moment. 2022 has only had one day so far with zero measured sunspots.

About the solar cycle, another marker is averaged monthly neutron counts, which have been trending downwards this year. Detected neutrons from cosmic rays are inverse to increased solar activity strengthening the sun's magnetosphere.
