06/09/2017 – Ephemeris – Watch the mini moon rise tonight

June 9, 2017 1 comment

Ephemeris for Friday, June 9th. Today the Sun will be up for 15 hours and 29 minutes, setting at 9:26, and it will rise tomorrow at 5:57. The Moon, at full today, will rise at 9:26 this evening.

In recent years we’ve talked about the super moon, when the full Moon appears especially large because it’s at perigee, or closest to the Earth at that time. Well tonight’s full Moon will be a the opposite, a mini Moon. The Moon reached apogee, its farthest from the Earth in it’s orbit at 6:21 last night, and 15 hours later, at 9:10 this morning the Moon was full. However I bet that when the Moon rises tonight that it will appear just as big as it always does, especially if you forget that it’s supposed to be a mini moon. The Moon is in an elliptical orbit of the Earth that this month varies from 252,500 miles (406,400 km) yesterday down to 222,400 miles (357,900 km) on the 23rd. Thanks to the Sun, and especially Jupiter and Venus, those distances change a bit every month. Tonight Saturn will be seen just below the moon.

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

11/14/2016 – Ephemeris – Watch the setting of the super moon this morning

November 14, 2016 Comments off

Ephemeris for Monday, November 14th.  The Sun will rise at 7:39.  It’ll be up for 9 hours and 36 minutes, setting at 5:15.  The Moon, at full today, will set this morning at 7:23 and will rise again at 5:53 this evening.

During the 6 to 7 o’clock hour this morning the Moon will be officially the closest super moon, most likely of your lifetime unless your 68 or older.  Super moon’s apparently only count when the Moon is closest to the Earth at full moon.  The Moon passes perigee, its closest point to the Earth once a month, but not always at full moon.  It happens that both October and December’s full moons are also super moons.  Rising and setting moon’s work the same way, to make the Moon appear even larger than it is.  This is an optical illusion, but go with it.  The Moon will be slightly farther away when it rises this evening.  Moon set will occur at 7:23 or thereabouts this morning while moon rise will be at 5:53 this evening, somewhat earlier east of Traverse City, later west.  Get out early if it’s clear.

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

Full super moon

The nearly full super moon at 8 p..m. EST (1 hr UT) last night. The fact that the moon is not quite full is the dullness on the Moon’s left side and a hint of a crater shadow. The Moon will be as full as it gets at 8:52 a.m. EST (13:52 UT). Credit Bob Moler
