Feb 3rd Sunspot changes

Feb 3rd. A cloudy day today only allowed me to take an image at 540 nm of the sunspots on the sun. Four active regions are shown and numbered. I have included an image from a few days ago to show the changes that have taken place in the spots (esp. AR 2936). Our atmosphere was too rough and cloudy today for a Halpha image. Single exposures with a Canon 550d camera attached to a 81 mm WO refractor and herschel wedge. Thanks for viewing.
