Sun on July 4th in H-alpha using my Sol'Ex Pro.
Next weekend, June 21 and 22, MARS60 is organizing their Journées de l'Astronomie Solaire de l'Oise et du Nord @ Baron (France). My objective is to meet other Sol'Ex users and what's the next level.
Sunspot AR4100 made his third tour around the Sun. I made images of all the three tours of this Sunspot. At first this was sunspot AR4055 in the beginning of April, on May 1, it was sunspot AR4079 and by end of May it was Sunspot AR4100.
