29th June A large sunspot
29th June ... It has been difficult to get any images of the Sun due to cloud and rain for a number of days. This morning there were still clouds but the occasional blue gap. I managed this image thru light cloud to show a large sunspot in the middle of the Sun's disc. I measured it at 125,000 km by 50,000 km in size. A large one for this cycle. Single exposure taken with a Canon 550d attached to a WO 81mm refractor with herschel wedge at 540 nm. Thanks for viewing.
