Sun with Sunspot AR2781 and AR2782?

This afternoon the Sun was covered with a very complex sunspot (AR2781). Also in the northern hemisphere I could observe a sunspot, but much smaller (AR2782?).

The picture is a combination of two pictures : ND3.8 and ND3.8 with Solar Continuum filter. Both pictures taken with Nikon D7500 and TAL200K f/8.5. Stacking and editing using CS4.

Supernova SN2020rcq



UGC 6930 (Uppsala General Catalogue of Galaxies) is part of the M109 group and located in constellation Ursa Major and about 50million ly away from Earth. The galaxy shows an "extra" star which is a supernova (SN2020rcq). The picture was taken with COAST C14 f/11 telescope on Tenerife. Exposure time 120 and no filters. I embedded a picture of UGC6930 from Simbad to compare with the Coast picture.
