Penumbral Lunar Eclipse of March 14

The first lunar eclipse of 2006 is a deep penumbral event best visible from Europe and Africa. First and last penumbral contacts occur at 21:22 UT and 02:14 UT (Mar 15), respectively. The Moon's path through Earth's penumbra as well as a map showing worldwide visibility of the event is shown in Figure 1. This particular event is unusual since it is a total penumbral eclipse. The whole Moon will lie completely within the penumbral shadow from 23:18 UT to 00:18 UT (Mar 15). According to Belgian eclipse expert Jean Meeus [1997] this is one of only five such events during the 21st century. Greatest eclipse occurs at 23:48 UT with a penumbral magnitude of 1.0565. At that instant, the Moon will stand midway in the penumbral shadow. The Moon's northern limb will lie 1.6 arc-minutes from the shadow's outer edge while the southern limb be 1.6 arc-minutes from the edge of the umbra.

Penumbral eclipses are difficult to observe, especially during the early and late stages. Nevertheless, a subtle yet distinct shading should be visible across the southern half of the Moon, especially during the two hour period centered on greatest eclipse.
