If you want to know if you can see it, depending on where you live, you can have a look at this map, provided by NASA's eclipse guru Fred Espenak:
In the central, white zone, you can, in principle, see the whole eclipse. The outer lines mark the phase of the eclipse at moonrise (for the Americas) or moonset (for Asia and Australia). The labels P1, U1, U2, U3, U4, and P2 correspond to the different phases of the eclipse, the entering of the penumbra (P1) and the umbra (U1), the begin and end of the total eclipse (U2 and U3), and the leaving of the umbra (U4) and penumbra (P4). So, if you live on the east coast of the US, the beginning of the total eclipse is just at moonrise (U2).
Most spectacular, of course, is the phase if total eclipse from 22:44:13 UT to 23:57:37 UT, with the moment of greatest eclipse at 23:20:56 UT.
Of course, a dense cover of clouds can spoil the show - that's what seems to happen here in Frankfurt am Main. For all of us who cannot see anything, either because of clouds, or because you are living in the "wrong" hemisphere, the German association of amateur astronomers has organised a
from a place in the Siebengebirge near Bonn. So far, they have more luck with the weather than I have. Let's hope that they, at least, will have clear skies tonight!
