01/31/2018 – Ephemeris – Lunar Eclipse happening now* and the bright planets for this week
* The Ephemeris radio program run at 6:19 a.m. and 7 a.m. EST will run during the lunar eclipse.
Ephemeris for Wednesday, January 31st. The Sun will rise at 8:02. It’ll be up for 9 hours and 47 minutes, setting at 5:50. The Moon, at full today, will rise at 6:15 this evening.
We have a lunar eclipse in progress this morning. Before the partial phase starts the Moon will have a dusky appearance because the Moon will be in the Earth’s outer penumbra shadow. The partial phase starts at 6:48 a.m. (11:48 UT), when the upper left part of the Moon will enter the Earth’s inner shadow, called the umbra. The Moon will be fully immersed in the shadow beginning at 7:51 a.m. (12:51 UT). It will probably disappear by then because the Sun will rise just after 8 a.m. and the Moon will set, at least in the Interlochen/Traverse City area at, 8:04.
Venus is our evening planet, but too close to the Sun to spot. At 7 a.m. Jupiter and Mars below left of it are in the south while Saturn is low in the southeast. Tomorrow morning Jupiter will rise at 2:20 a.m., Mars will follow at 3:25. Last of all Saturn will rise at 5:50 a.m.
The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
