APOD has a very cool picture of the sun sliding past the moon over the Golden Gate on Monday. I made a pinhole camera with the helpful suggestions of eyelessgame ( I knew the theory but didn't know that aluminum foil makes for a better hole and the like) and went out to watch occasionally. The neatest part was an effect that I had heard of but never seen -- the dapple of sunlight on our front porch turned into a constellation of crescent moons, from the narrow beams of sunlight through the leaves. I got a couple of pictures, though the effect doesn't really come through.
I do wish I had had welder's glass -- people looking at it directly said that several sunspots were visible.
