02/04/2014 – Ephemeris – Viewing the crescent moon tonight

February 4, 2014

Ephemeris for Tuesday, February 4th.  The sun will rise at 7:57.  It’ll be up for 9 hours and 57 minutes, setting at 5:55.   The moon, 2 days before first quarter, will set at 12:05 tomorrow morning.

The Moon is now beginning to dominate the sky.  In small telescopes one of my favorite craters is peeking into sunlight at the sunrise line, astronomers call it the terminator.  This one is called Theophilus.  Tonight it should be a ring of the circular ramparts lit by the sun as the evening progresses, in the center of which is the central peak just catching sunlight.  Theophilus is at the edge of the small Sea of Nectar or Mare Nectaris.  For those with small telescopes who want to learn more about how to use them the Grand Traverse Astronomical Society will host a Telescope Clinic at Northwestern Michigan College’s Rogers Observatory on Friday starting at 8 p.m.  You can bring your telescope.  It’s free, but for the star party the College requests a small donation.

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