It was a lovely sunny day here in Ottawa.  My seeing as per normal was best (poor 2/5) in the early morning and shaky/wavy by 9:30 AM.  Full solar disc was easy - able to stack about 50% of the frames.  Close ups were more difficult - able to stack 12 frames out of 1600 = Lucky Imaging.

 

Full Solar Disc
