LARGE SUNSPOTS Taken by Maximilian Teodorescu on July 13, 2023 @ Institute of Space Science, Magurele, Romania






We have two large sunspot groups on the Sun these days: one is very large (3363), but not so active, while the other one (3372), a new one actually, is very active. 355mm Newtonian, ASI174MM, poor to fair seeing.
