At about 7:00 this morning, I happened to notice two black dots in the middle of the sun. With a telescope (an ordinary kind), I could clearly see 4 groups of sunspots on the sun. Sunspots that can be seen directly with the naked eye should be very large, at least larger than the diameter of the Earth, I think.
This is the first time I've seen sunspots.
