Shown here are three images of sunspots, each taken 48 hours apart. Dates 22nd, 24th and 26th March 2023.
The prominent spot is AR3256 but there are others that stand out. Sky conditions varied - the last image was taken thru light cloud.
All images are single exposures with a Canon 550d camera attached to a 81 mm WO refractor with herschel wedge at 540 nm.
Thanks for viewing.
27th March 3 days of sunspots
