A second day of sun 14 April 2023

There was a small amount of sun this morning after some initial clouds cleared and before they rolled back in. Unfortunately by the time it had cleared (about 11am local time) the seeing was averaging 3.5 arc seconds with a standard deviation of 1.0. This was a pity as it was a really interesting disk with many proms, filaments and active regions. It wasn't really worth setting up much equipment so we just did a two panel Ha mosaic of the full disk, and a full disk in 393nm. While we were there we popped in a 1.9x barlow and did an four panel 393nm mosaic as well. We couldn't make a small version of the mosaic to post here.
