The penumbral eclipse lasts for 6 hours and 5 minutes. The partial eclipse lasts for 3 hours and 40 minutes. The total eclipse lasts for 1 hour and 2 minutes. Maximum eclipse is at 01:27:20 UT.
During this eclipse the Moon will be at apogee, making it very small. At maximum eclipse it will be 0.498° in apparent diameter, which is 6.3% 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 maximum eclipse, when it will be visible within the bright area on the map. 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. 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.
