11/07/2019 – Ephemeris – The gibbous Moon tonight

November 7, 2019 Comments off

Ephemeris for Thursday, November 7th. Today the Sun will be up for 9 hours and 55 minutes, setting at 5:23, and it will rise tomorrow at 7:30. The Moon, 3 days past first quarter, will set at 3:13 tomorrow morning.

Every night when we look at the Moon the sunrise terminator has moved farther west on the Moon which is to 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. South of all that is the odd shaped crater Schiller.

01/25/2018 – Ephemeris – The Moon tonight: Copernicus on the terminator

January 25, 2018 Comments off

Ephemeris for Thursday, January 25th. The Sun will rise at 8:09. It’ll be up for 9 hours and 32 minutes, setting at 5:41. The Moon, 1 day past first quarter, will set at 2:48 tomorrow morning.

Let’s take a look at our slightly gibbous moon, just a day past first quarter with binoculars or a small telescope. The terminator, in this case the sunrise line will appear to cross the crater Copernicus to the right of the Moon’s center if you’re viewing it right side up. To the North across the Sea of Showers, or Mare Imbrium is the large flat floored crater Plato. South of Copernicus is a recently named sea, Mare Cognitum, the Known Sea, after the first successful close photography by the Ranger 7 spacecraft in 1964. South of the is Mare Nubium, the Sea of Clouds. South of that are the lunar highlands with the stark crater Tycho and the huge crater Clavius with an arc of craters of decreasing size within it.

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

04/27/2015 – Ephemeris – Two large craters on the Moon for binoculars or a small telescope

April 27, 2015 Comments off

Ephemeris for Monday, April 27th.  Today the Sun will be up for 14 hours and 3 minutes, setting at 8:42.   The Moon, 2 days past first quarter, will set at 4:04 tomorrow morning.  Tomorrow the Sun will rise at 6:37.

After taking a look, last week, at some early results from the two spacecraft approaching dwarf planets now, Dawn at Ceres and New Horizons nearing Pluto, let’s get back to our sky and our Moon.  Time to get out that telescope or powerful binoculars.  The terminator which now is the sunrise line will be cutting through the middle of the crater Copernicus at 10 in the evening.  Copernicus, near the Moon’s equator hit a flat lunar sea, so it’s quite conspicuous.  Another crater near the Moon’s southern pole is conspicuous because it’s so big.  It’s Clavius, with an arc of diminishing sized craters within.  It will be completely in sunlight being uncovered slowly now by the terminator.

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

10/02/2014 – Ephemeris – The gibbous Moon tonight

October 2, 2014 Comments off

Ephemeris for Thursday, October 2nd.  The sun will rise at 7:41.  It’ll be up for 11 hours and 39 minutes, setting at 7:21.   The moon, 1 day past first quarter, will set at 1:50 tomorrow morning.

Tonight the moon will be featuring some of my favorite lunar landmarks, and if you spend any time looking at the moon with a small telescope, they become yours.  The place to look is at the terminator, the sunrise line on the moon.  In the north not far from the terminator is the walled plain called Plato.  A bit farther away is a gash in the lunar Alps mountains caller the Alpine Valley.  Near the center of the terminator and split by it is the fabulous  crater Copernicus with a triple central peak which should poke into sunlight.  Near the south pole is the large crater Clavius with an arc of decreasingly smaller craterlets on its floor.  A bit north of that is the crater Tycho, which is more prominent when the moon is full than it is now.

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

05/29/2012 – Ephemeris – The moon tonight

May 29, 2012 Comments off

Ephemeris for Tuesday, May 29th.  Today the sun will be up for 15 hours and 16 minutes, setting at 9:18.   The moon, 1 day past first quarter, will set at 2:38 tomorrow morning.  Tomorrow the sun will rise at 6:01.

The moon tonight is a wonderful sight for binoculars or a small telescope.  There are some very nice craters now revealed near the terminator, the line between day and night on the moon.  The terminator in the two weeks between new and full is the sunrise line on the moon.  From the top or north on the moon is the flat floored crater Plato Then about midway down the moon and right on the terminator is the beautiful crater Copernicus.  Then to the south end of the moon is the bright and crisp crater Tycho.  Its splash marks called rays will be better revealed at full moon.  At the bottom of the moon, just coming into light is the huge crater Clavius.  A telescope will reveal smaller craters within.

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