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.

03/05/2015 – Ephemeris – Tonight’s moon is the smallest full moon of the year

March 5, 2015 Comments off

Ephemeris for Thursday, March 5th.  The Sun will rise at 7:13.  It’ll be up for 11 hours and 21 minutes, setting at 6:35.   The Moon, at full today, will rise at 6:48 this evening.

We’ve heard all about the supermoon, when the moon is at its closest.  This is supposedly best seen when the full moon is rising.  Of course the rising moon or sun, or the setting of these bodies look larger than normal due to an optical illusion.  Well tonight’s full moon is the opposite.  The Moon is at apogee, which is the farthest it gets in its orbit of the Earth.  It’s 253 thousand miles (406 thousand km) from Earth.  So the Moon should be, let me see, a mini-moon?  So the Moon should appear small as it rises tonight.  So if it’s clear tonight you might check out the moon.  Does it appear as large as it usually does?  Or does it appear smaller?  The moon, being alone in the sky lacks anything else to compare its size to.  It makes estimations difficult.

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