The Sky This Week - Thursday March 12 to Thursday March 19
The Last Quarter Moon is Saturday March 14.
Venus is easy to see low above the western horizon in the twilight. At civil twilight, half an hour after sunset, it is around one and a half hand-spans above the horizon. Venus is also above Mars.
Mars is low in the western twilight sky and is effectively lost to view.
Jupiter is now easily seen in the evening sky. It is the brightest object above the north-eastern horizon when twilight ends. It is not far from the bright star Regulus in the sickle of Leo (this forms the head of the constellation of the Lion). It is also not far from the rather nice Beehive cluster in Cancer, and looks very good in binoculars.
Jupiter was at opposition, when it is biggest and brightest in our sky, on 7 February, but it will be an excellent object for may weeks to come. Jupiter is visible all night and is high enough for decent telescopic observation from around 10 pm. Jupiter's Moons will be putting on a good display in both binoculars and small telescopes.
Saturn climbs still higher in the morning sky. It is now easily visible well before twilight near the head of the constellation of the Scorpion not far from the bright red star Antares. The sight of the distinctive constellation of the Scorpion curled above the horizon, with bright Saturn in its head, is very nice indeed.
Saturn is now rising a little before midnight, but it will be later in the month before we get a good look at it in the evening. Saturn is visited by the waning Moon on the 13th.
Mercury is high in the morning twilight and should be reasonably easy to see over a hand-span above the horizon an hour before sunrise. On the 19th it is visited by the crescent Moon.
The Globe at Night light pollution survey for March has started.
There are lots of interesting things in the sky to view with a telescope. Especially with Jupiter just past opposition. If you don't have a telescope, now is a good time to visit one of your local astronomical societies open nights or the local planetariums.
