Lets see what bright planets are out this week.  Venus is now brilliant low in the west southwestern sky in evening twilight.  It will set at 9:24 p.m.  Saturn is about 8 degrees above and to the left of Venus.  That’s a bit less that the width of a fist held at arm’s length.  It has a date with Venus on the 18th.  Saturn will set at 9:58 p.m.  After midnight Jupiter will rise at 1:45 a.m. in the east northeast.  Jupiter is seen among the stars of Gemini this year.  The red planet Mars will rise at 3:43 a.m.  Currently it is moving rapidly eastward through Cancer.  At about 6 a.m.  Jupiter will be the brightest star-like object in the east, with Mars visible below and left by two and a half widths of your fist held at arm’s length.

Ephemeris for Wednesday, July 24th.  The sun rises at 6:20.  It’ll be up for 14 hours and 56 minutes, setting at 9:16.   The moon, 2 days past full, will rise at 10:12 this evening.

07/30/2013 – Ephemeris – Mercury appears in the morning

July 30, 2013 Comments off

Ephemeris for Tuesday, July 30th.  The sun rises at 6:27.  It’ll be up for 14 hours and 43 minutes, setting at 9:10.   The moon, 1 day past last quarter, will rise at 1:23 tomorrow morning.

Mercury is joining the morning planets Jupiter and Mars now.  This morning is the time of its greatest elongation or separation from the sun of 20 degrees, but this planet will actually brighten as it starts its journey back around the sun.  Mercury’s phase at greatest elongation is half illuminated.  As it moves back around the sun the phase becomes fuller.  To find Mercury it’s best to use binoculars.  At around 5:30 look to the east northeast on a very low horizon. First locate Jupiter, the brightest and highest of the three.  Then look below for reddish Mars.  Once found, Mercury can be located by extending a line one and a half times further than Mars.  These planets can be seen until 6 a.m. or a bit later.
