Tonight's the night. If skies are clear enough, Marylanders will get get their first look at a total lunar eclipse since October 2004. The moon will already be fully eclipsed when it rises over the eastern horizon around 6 p.m. Its darkened disk and the lingering twilight might make it hard to spot at first. But we'll have until about 7 p.m. to see that weird, coppery glow of totality. Then Luna will begin emerging from Earth's shadow into full sunlight. Show's over at 8:11 p.m.
