Heya,

 

It rained yesterday and today is not much better, I saw a small moment this morning between big clouds and waited a few out and tried some fast imaging in sucker holes. I didn't bother measuring seeing as the clouds just make it a mess anyways. On the screen the seeing was good enough (1.3~1.4 arc-seconds at the least based on this image scale) for the image scale between clouds, so lucky imaging prevails. AR2827 is still fantastic, great penumbra now on that spot and its mottling and filaments are great. AR2829 has really woken up and went from being a disturbance to something nice too over night it seems, great long plage and mottling dragging behind it too. There's a nice grouping of prominences on the North Eastern limb, a couple of arches.
