03/22/2016 – Ephemeris – Really difficult lunar eclipse to spot at sunrise*

March 22, 2016

Ephemeris for Tuesday, March 22nd.  The Sun will rise at 7:41.  It’ll be up for 12 hours and 17 minutes, setting at 7:58.   The Moon, 1 day before full, will set at 7:48 tomorrow morning.

The Paschal full moon is tomorrow morning.  I’ll explain more about it on Thursday as we get closer to Easter this coming Sunday.  However as the Moon sets for our region it will be in eclipse.  It’s not a big deal partial or total lunar eclipse, but a penumbral eclipse, where the Moon slips into the Earth’s outer shadow, where the Sun’s light is partially cut off by increasing amounts from the edge of the penumbra to the totally blocked umbral shadow.  As the Moon is setting tomorrow morning after 7:30 a.m., it may be showing a dusky lower left edge, the part of the Moon closest to the center of the Earth’s shadow.  It might difficult to see the effect, though the bright skies may actually help by washing out the light of the Moon.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

* The eclipse, such as it is, will not be visible east of us around 86º west longitude, and be more visible west of us.

This eclipse, however the Moon will dip only into the outer penumbra.

What the progress of the eclipse is like at 7:40 a.m. The sky will be bright because the Sun will be rising at that time. Created using Cartes du Ciel (Sky Charts).
