A Quick and Dirty Full Disk: 9th February

I got away from work early on Friday afternoon, and to my surprise the sun was visible in the slimmest of gaps, that is viewing with the scope through an open front door with passing cloud!  I decided to try the ED60 f6 with the Lunt wedge for a quick view.  The air was boiling away with the temperature differential in the open door, and was difficult to find focus - i'm not even convinced I did!  Still I was able to see AR12699 which is the largest active region for a while in this declining phase of the solar cycle.  Camera was the PGR Ch3 with a green filter and UV/IR cut.  Better than nothing, especially as that was what I was expecting for a while yet!
