I managed to get 3 consecutive images of the sunspots on 19, 20, 21 June despite the poor weather conditions. Lots of cloud and rain but I found a couple of gaps each day. Mostly small sunspots at the moment. The most prominent active regions are AR3335, 3339 and coming into view on the eastern limb AR3341 looks promising. All images are single exposures with a Canon 550d attached to a WO refractor and Herschel wedge at 540 nm.
Thanks for viewing.
