Ca II K and Ha FDs 9th April 2021

Post by Carbon60 »

A couple of quick FDs captured at lunchtime today in Ca II K and HA. The long filament visible in HA is a little disjointed, but remains pretty impressive.

Very nice disks Stu, you can just about make out the 'shadow' of that filament on your CaK disk. Friday was just grey and drizzly here, so resorted to rule of 6 beer gardening instead...
