The entirety of the moon surface will be in Earth's shadow and start to glow red a couple hours later, a little after midnight. From the article: 'A lunar eclipse occurs when the sun, moon, and Earth align so that Earth's shadow falls across the moon's surface. Monday night's lunar eclipse is a total eclipse, which means Earth's shadow will cover the moon completely. The moon won't be blacked out by our planet's shadow. Instead, it will take on a reddish hue — anywhere from a bright copper to the brownish red of dried blood.'
