09/17/2018 – Ephemeris – The Moon Tonight and the Jade Rabbit

September 17, 2018 Comments off

Ephemeris for Monday, September 17th. The Sun will rise at 7:24. It’ll be up for 12 hours and 25 minutes, setting at 7:49. The Moon, 1 day past first quarter, will set at 1:03 tomorrow morning.

Now is a good time to point that small telescope or binoculars toward the Moon. The gray seas on the right side of the moon depict the neck, head and ears of the Jade Rabbit. It’s curled up body is on the night side of the Moon to the left. The rabbit is upside down as we see him with the naked eye or binoculars. The Sea of Serenity is the upper part of his body, the head is the Sea of Tranquility. A bay south of Tranquility and the Sea of Nectar is one ear and the Sea of Fertility is the other ear. The Jade Rabbit is related to the Chinese Mid-Autumn Festival which occurs at our Harvest Moon. It’s on September 24th this year. Another amateur astronomer and myself brought telescopes to the local festival last year to view the Jade Rabbit on the Moon.

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

09/25/2017 – Ephemeris – Lets look at the Moon tonight

September 25, 2017 1 comment

Ephemeris for Monday, September 25th. The Sun will rise at 7:33 a.m. It’ll be up for 12 hours exactly, setting at 7:33 p.m. The Moon, 2 days before first quarter, will set at 10:52 this evening.

Let’s take a look at the crescent Moon tonight. It will be fairly low in the southwestern sky this evening. Four of the gray lava plains called seas are now visible in binoculars or small telescopes. Nearest the right limb of the Moon is the Sea of Crises, next nearest if the Sea of Fertility. A small sea next to that is the Sea of Nectar. Above that, mostly exposed to sunlight is the Sea of Tranquility. The Sun is just rising at Tranquility Base, where Apollo 11 landed, where the Lunar Module’s descent stage still lies, forlorn and empty. Below that is the beautiful crater Theophilus with its central peak. It is 61 miles (101 km) in diameter, and its crater walls rise over 13,000 feet (4,400 meters) above the crater floor.

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

Ephemeris for Thursday, October 6th. The Sun will rise at 7:47. It’ll be up for 11 hours and 25 minutes, setting at 7:13. The Moon, 3 days before first quarter, will set at 10:44 this evening.

Tonight the waxing crescent Moon will appear between Saturn on the right and Mars on the left. In a small telescope the Sea of Tranquility is now mostly in daylight. The Sun will rise on the Apollo 11 landing site about one this afternoon. The landing site cannot be seen from the Earth, it’s artifacts are too small. The Lunar Reconnaissance Orbiter has to get down to about 15 miles altitude to photograph them. The craters of Theophilus, Cyrillus and Catharina are seen to the south of Tranquility. Just south of them there looks like a wrinkle in the Moon surface. It’s the Altai Scarp, which is named for the Altai mountains of central Asia. The three craters border the small Sea of Nectar. The lunar seas are basins of solidified lava.

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

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

February 4, 2014 Comments off

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.
