The timings of the phases of the eclipse are as follows. You will be able to see each phase of the eclipse if the Moon is up at the corresponding time as seen from your location; however the penumbral phase will be very difficult to see in practice, so you may want to start watching at the partial phase:
|Penumbral eclipse begins:||19:42:53 UT|
|Partial eclipse begins:||20:55:17 UT|
|Total eclipse begins:||22:15:05 UT|
|Maximum eclipse:||22:41:54 UT|
|Total eclipse ends:||23:08:45 UT|
|Partial eclipse ends:||00:28:34 on 21 Dec UT|
|Penumbral eclipse ends:||01:40:51 on 21 Dec UT|
During this eclipse the Moon will be just 4 days past apogee, making it fairly small. At maximum eclipse it will be 0.508° in apparent diameter, which is 4.3% smaller than average. The statistics page has information on the ranges of the sizes of the Sun and Moon.
This map shows the visibility of the eclipse at various stages. The bright area in the middle will see the whole eclipse; the coloured bands to the right will see the start of the eclipse, and those on the left will see the end. Note that the map is approximate, and if you are near the edge of the area of visibility, the moon will be very close to the horizon and may not be practically visible.
You can use the zoom controls to zoom in and out, and pan to see areas of interest. Hover your mouse over the tags to see what will be visible from each area on the map. The green marker in the centre shows where the Moon will be directly overhead at maximum eclipse.

The Sun and Moon distances are shown in km, and as a percentage of their minimum - maximum distances; hence 0% is the closest possible (Earth's perihelion, or the Moon's closest possible perigee) and 100% is the farthest (aphelion, the farthest apogee). The statistics page has information on the ranges of sizes of the Sun and Moon.
