It's a day of relatively-unusual natural phenomena -- first the earthquake this morning and then, less than 24 hours later, there's going to be a total eclipse of the moon.

The lunar eclipse will be visible throughout California, but only for those of you who are up from the hours of 1:51 a.m., when the partial eclipse will start, through 5:24 a.m., when dawn starts up. If you are up that late, the total eclipse goes from 2:52 a.m. through 4:22 a.m. The moon'll be glowing red, and since it's not the sun, it's okay for you to look at it with the naked eye (or with binoculars or a telescope) and you won't burn out your retinas like your fourth-grade science teacher had warned you. It's expected to be one of the best lunar eclipses in years.

The Chabot Observatory is having an all-night party to celebrate the eclipse, with telescopes and hikes for nice panoramas. (If it's foggy, they'll run a simulation of the event inside.)

If you miss this one, the next lunar eclipse'll be on Feb. 21 -- it won't last as long, but it'll be in the early evening hours so you won't have to take special measures to see it. Meanwhile, of course now we've got "Total Eclipse of the Heart" running in our head, which we're sure we'll be stuck singing all day. Curse you, earworm!
