Post by Carbon60 »

Hi all,

Just a couple of FDs in Ha and Ca II K showing a very quiet Sun.

Hopefully this is only a short-lived pause in cycle 25 activity.

Thanks for looking.

Stu.

Quiet just about describes that perfectly indeed :)

Good to see you managed to squeeze a session in, Stu. Nice and clean looking disks.
