Sunspots 23rd Jan

23rd Jan. A nice steady and clear morning allowed me to take this pic of the new sunspot group AR2799 together with older groups AR2797 and 2798. Most activity this year has been in the southern hemisphere but this new group is in the north. All spots are small. Taken with a Canon 550d on a WO 81 mm...

Re: Solar prom of 7th Jan

Thank you everybody for your kind comments. A hot night last night here in SE Australia with 24°C min and 37°C during day. Very hot due no doubt to the old Sun. Cheers John W.

Re: 29th Dec Sun images
