In even the smallest telescopes Jupiter’s four largest moons can be seen. They shift positions night from to night and sometimes even as you watch. Jupiter will set at 4:09 a.m. Saturn can now be seen late in the evening after it rises in the east-southeast at 10:15 p.m. At 5 a.m. both Saturn and Venus will be in the morning twilight. Brilliant Venus will be low in the east tomorrow morning after rising at 4:05 a.m.

04/21/2017 – Ephemeris – Mars is passing south of the Pleiades today

April 21, 2017 Comments off

Ephemeris for Friday, April 21st.  The Sun rises at 6:47.  It’ll be up for 13 hours and 47 minutes, setting at 8:35.  The Moon, 2 days past last quarter, will rise at 4:54 tomorrow morning.

Mars in its ever eastward trek through the constellations of the Zodiac is now just south of the Pleiades or Seven Sisters star cluster in the western evening twilight.  By 10 p.m. Mars will be 10 degrees above the western horizon.  That’s the width of a fist held at arm’s length.  Because of our location on the Earth, the setting sky is tilted, so Mars being south of the Pleiades is to the lower left of it.  The bright star Aldebaran, now brighter than Mars is to the left of it with the V-shaped star cluster called the Hyades, in mythology, half sisters of the Pleiades, filling out the face of Taurus the bull.  Mars will finally be overtaken by the Sun on July 26th.  After that it will spend more than a year to come closer to us than at any time since August 2003.

First star party of the year at the Sleeping Bear Dunes National Lakeshore

Tomorrow night the Rangers of the Sleeping Bear Dunes National Lakeshore and the Grand Traverse Astronomical Society will host a Star Party at the Dune Climb featuring the planet Jupiter, and the stars of spring.  It starts at 9 p.m.

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

Mars passes the Pleiades
