10/11/2016 – Ephemeris – Looking at the Moon tonight

October 11, 2016

Ephemeris for Tuesday, October 11th.  The Sun will rise at 7:53.  It’ll be up for 11 hours and 10 minutes, setting at 7:04.  The Moon, 2 days past first quarter, will set at 3:26 tomorrow morning.

We looked at the Moon in the last program, now 24 hours later the sunrise terminator has moved farther west, our east uncovering more landscape.  The Moon rotates once in about 29 ½ days in relation with the Sun.  This is the same time it orbits the Earth from new Moon to the next.  We call that a lunation or lunar month.  Near the upper left corner of the Moon is what looks like a half crater.  It’s called Sinus Iridium, the Bay of Rainbows.  It’s at the edge of Mare Imbrium or Sea of Showers.  To the south cut by the terminator is Oceanus Procellarum, the flat Ocean of Storms.  South of that is the small Mare Humorum, the Sea of Vapors.  Between then is a distinctive crater Gassendi.  South of all that is the odd shaped crater Schiller.

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