04/06/2016 – Ephemeris – Mercury makes its spring appearance in the west – Plus Jovian moon hijinx

April 6, 2016

Ephemeris for Wednesday, April 6th.  The Sun will rise at 7:13.  It’ll be up for 13 hours and 3 minutes, setting at 8:17.   The Moon, 1 day before new, will rise at 7:30 tomorrow morning.

Let’s check out the whereabouts of the bright naked eye planets.  Mercury is in the west-northwest, very low to the horizon, setting at 9:35 p.m.  Jupiter is in the southeast in the evening, and will pass due south, astronomers call it a transit, at 11:45 p.m., and will set at 6:16 a.m.  It’s below the stars of Leo this year.  Binoculars can make out some of Jupiter’s moons, but a telescope is required to see all four bright moons and Jupiter’s cloud formations.  Mars will rise next at 12:31 a.m. in the east-southeast.  It’s above Scorpius but moved into western Ophiuchus now.  Saturn will rise at 1:06 a.m. in the east-southeast.  It’s just left of Mars.  Its rings are a telescopic treat.  Venus will rise at 6:47 a.m. due east.

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