Solar activity 12.04.2025 (open house at PRAO FIAN)

On Saturday during the day, the Sun pleased with its activity. Region No. 4055 was especially interesting. I even managed to take several photos (MAK 102/1300 mm, Nikon D5300, ND 0.6 filter). The Wolf number was at the level of 115 (https://sidc.be/SILSO/eisnplot). Thanks to the organizers for the reception, it's already my fifth time at PRAO on open days, I really like the atmosphere!
