Re: AR2822 WL (High Res), CaK, HA | May 14th 2021

Getting a short exposure time, ie less than 10ms nearer 1ms helps in my experience of granulation imaging, even increasing gain to achieve this, and Baader Continuum filter is helpful

28th April flare

Sunny and breezy but 4 arcsec average seeing on the SSM. I collected frames at 30 second intervals for 1.5 hours but noticed some activity on GONG right at the end so I caught a small flare which shows up on the X ray plot as B1.2 at 12.40GMT.

20th April

Long enough sunny bits to get the 150mm PST mod out after a long gap. It all worked surprisingly and I got rough and ready 6 minute animations of the two ARs, not much happening but good to try it out again.

10th April

Sunny but poor seeing, some activity to see, the prominence on the south is moving about. My animation is 7.5 minutes and something is just about visible!

Hazy but lovely weather today. The big prominence needed an exposure tweak to make it more visible.
