Solstice eclipse

If you can stay up tonight (well, depending on where you live, you might not have to stay up very late), you can see a natural wonder: a lunar eclipse on the solstice.

The full moon doesn't occur on the solstice every year. The last ones were in 1999 and 1980. And the next one won't be until 2094. That one will be an eclipse - though you'll need to be pretty young now to have a shot at that one! Still, it's not as long a gap as it might have been - the most recent solstice eclipse was ... 1638.

At any rate, if you live in North America you can watch the whole thing. On the East Coast, it begins half an hour after midnight on Tuesday; on the West Coast, it begins around 9:30 p.m. PST Monday. Maximum eclipse is at 3:17 a.m. EST/12:17 a.m. PST.
