11/18/2013 – Ephemeris – Mercury is visible in the morning near Comet ISON

November 17, 2013

Ephemeris for Monday, November 18th.  The sun will rise at 7:43.  It’ll be up for 9 hours and 28 minutes, setting at 5:11.   The moon, 1 day past full, will rise at 6:12 this evening.

The planet Mercury is now visible in the morning sky rising at 5:59 a.m.  While Mercury is only 19 and a half angular degrees from the sun its direction is closer to the vertical than Venus and the other planets are in the evening sky.  That situation will change in 3 months when evening planets will be favored.  The star Spica will be above and right of Mercury, along with Comet ISON which will be nine moon diameters below and right of Spica, about a third of the way to Mercury tomorrow.  Comet ISON will rise at 5:19 tomorrow morning.  Morning twilight will begin at 6:08 tomorrow morning, but remember the moon will still be nearly full so the sky won’t be really dark before twilight begins.   The Moon is light pollution you can’t get around.

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


Mercury and Comet ISON

Mercury and Comet ISON at 6:30 a.m. on November 19, 2013. Created using Stellarium.

Comet ISON’s tail may be visible to the naked eye or in binoculars after it’s outburst last Thursday night.  The comet may be able to live up to its advance billing after all.
