08/23/2016 – Ephemeris – Mars, Antares and Saturn line up

August 23, 2016

Ephemeris for Tuesday, August 23rd.  The Sun rises at 6:55.  It’ll be up for 13 hours and 39 minutes, setting at 8:34.  The Moon, 1 day before last quarter, will rise at 11:49 this evening.

Tonight if you look out to the southwest, you will see a nearly perfect, nearly vertical line of bright stars.  But two of these are planets.  The brightest is the red planet Mars.  Below is it’s rival, the red giant star Antares.  Above is the ringed planet Saturn.  Tonight Mars will be just to the right of the Saturn Antares line.  After they set tonight and before we see them tomorrow night Mars will have moves  to be just out of the line to the left.  I hope it’s clear tonight so I can get a picture of them.  A digital camera on a tripod with a low f-stop, and a high ISO speed with a shutter open for maybe 15 seconds ought to do it.  Manually focus on infinity.  Dark skies confuse auto focusers.  And turn the flash off.  Try it again tomorrow night.

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