01/27/2014 – Ephemeris – Mercury’s back in the evening sky now

January 27, 2014

Ephemeris for Monday, January 27th.  The sun will rise at 8:06.  It’ll be up for 9 hours and 37 minutes, setting at 5:44.   The moon, half way from last quarter to new, will rise at 5:47 tomorrow morning.

Mercury is now making an appearance in the evening sky.  It will have its greatest elongation or angular separation from the sun on Friday of 18.4 degrees.  Mercury has a markedly elliptical orbit.  Unfortunately both the best times to view Mercury from the northern hemisphere of earth, late summer and autumn mornings and late winter and spring evenings, Mercury is near perihelion or closest point in its orbit to the sun.  The southern hemisphere, which has seasons opposite from ours, has the  same viewing opportunities in late summer and autumn mornings and late winter and spring evenings. Only for them Mercury is near aphelion or its farthest from the sun, so this planet can be seen just outside of twilight, where we don’t have that luxury.

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

Mercury will move to the top of the orbital loop Friday about 5 a.m. and descend to the right.  The Mercury image will be posted Wednesday again.
