01/17/2019 – Ephemeris – There will be a total eclipse of the Moon Sunday night the 20th

January 17, 2019 Comments off

Ephemeris for Thursday, January 17th. Today the Sun will be up for 9 hours and 15 minutes, setting at 5:30, and it will rise tomorrow at 8:14. The Moon, 3 days past first quarter, will set at 5:31 tomorrow morning.

There will be an eclipse of the Moon late this Sunday evening and into early Monday morning. For what it’s worth it’s also a so-called super moon dropping down to 222 thousand miles (357,300 km) from the Earth about 3 p.m. Monday, 15 hours after mid-eclipse. At about 10:34 p.m. Sunday night the lower left edge of the Moon will begin to enter the Earth’s inner shadow the umbra starting the partial phase of the eclipse. The Moon will be totally immersed in the shadow by 11:41 p.m. and will probably appear a coppery color. Totality will end at 12:43 a.m. Monday morning when the left edge of the Moon peeks out into sunlight. This begins the ending partial phase which itself will end at 1:51 a.m.

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

Eclipse times

UT times are for January 21st. which starts at 7 p.m. EST the 20th.  EST times are for the nearest minute.

Note that at contacts P1 and P4 nothing will be visible out of the ordinary.  As the Moon moves to the U1 contact the left edge of the Moon will appear noticeably dusky as more and more sunlight is cut off.

The reddish color of totally eclipsed Moon is due to all the sunrises and sunsets happening at that time on the Earth.  The Earth’s atmosphere bends the Sun’s light into its shadow.
