Sunspot group 2804 was the only one that I could see today. Some of AR2805 appears in Ha light but not visually. Single exposure (at 540 nm) taken thru a Canon 550d camera and Herschel wedge attached to a WO 81 mm scope. Western limb shown. I've included a second image in Ha from yesterday to compare (both have N up). Thanks for viewing.
