David Smith

Sunday 18th May Solar Activity

Recommended Posts

Made an early start and found clear-ish skies, a bit hazy but much better than the last 2 days. Didn't expect much with all the active regions now on the far side but I was pleasantly surprised!

White light was quiet as expected although the seeing was not bad at all and visually the granulation was quite impressive. I didn't do close ups with the ASI today as there were no AR's, just an FD via DSLR.

Ca-K disk looked pretty quiet too

Then I switched to look for proms and found a whole bunch of stuff going on. After reading a few articles / posts recently I had a play around with binning 2x today. This really helps capture proms with shorter exposure times and faster frame rates. The first 2 images below are at native 1000mm focal length, the last 2 using the 2.5x barlow.

A bonus session today for sure, very cloudy here in Bedfordshire. Nice to see some Ca-K proms, looks like we back to a spotless Sun again for a while.
