Consider a planetarium program to help you plan your observations. There are many commercial products available, and an excellent program (STELLARIUM) is available free at http://www.stellarium.org/.
To close out the month of March, Mars (which is appropriately named for Mars) and Mercury make an appearance in the early night sky, as the crescent Moon visits Taurus.
Comet 41P/Tuttle-Giacobini-Kresak (“T-G-K”) is now about magnitude 7. It is a large object but rather diffuse, and should be visible in small telescopes. It is expected reach 6th magnitude at the end of March and stay about that bright through April. For details see the Sky & Telescope article and finder chart at http://www.skyandtelescope.com/observing/comet-41pt-g-k-glows-green-for-st-paddys-day/.
Monday (March 27)
New Moon at 8:57 p.m. MDT.
Wednesday (March 29)
Try to spot the thin crescent Moon low in the west, about 10 degrees below Mars (about a fist width held at arm’s length), as shown in the above diagram.
Saturday (April 1)
Mercury is at its highest sunset altitude of the year. Look low in the west (see above diagram) about 45 or 60 minutes after sunset.
Mercury (in Pisces):
Mercury is having its best apparition of the year. Don’t miss it – look in the evening twilight, low and due west.
Venus (in Pisces):
Venus was at inferior conjunction on March 25th when it passed just north of the Sun on its way to becoming a morning “star.”
Mars (in Aries):
Look for a faint orange “star” low in the west during late twilight.
Jupiter (in Virgo):
Jupiter rises a little after dark, is high in the southeast about 11 p.m., and dominates the southwestern sky before dawn. The bright star below it is Spica (in Virgo). Jupiter reaches opposition on April 7th, which is its closest approach during this apparition.
Saturn (in Sagittarius):
Look in the south-southeast in the early morning hours, to the upper right of the Sagittarius “teapot.” Reddish Antares is about 19 degrees to Saturn’s right (a little less than the width of your fist with your thumb extended).
Uranus (in Pisces):
Lost in the morning glare.
Neptune (in Aquarius):
Lost in the evening twilight.
