14th Jan. There are lots of sunspots visible today - double the number of groups from 2 days ago. A large spot AR3190 has appeared on the E limb and AR3186 is prominent. I have posted two images - the first is from 12th Jan and the second from today (14th) so you can see the changes easily.
Both are single exposures with a Canon 550d camera on a WO 81 mm refractor with Herschel wedge at 540 nm. Temp is 38°C today !
Thanks for viewing.
