The Sky This Week - Thursday March 8 to Thursday March 15
Evening sky looking east as seen from Adelaide at 11:00 pm local daylight saving time on Sunday March 11 showing Mars and the Moon and Saturn near Spica. Similar views will be seen elsewhere at the equivalent local time. The inset shows the telescopic appearance of Saturn and it's Moons at this time. Click to embiggen.
The Last Quarter Moon is Thursday March 15.
Mars is in the constellation of Leo. It is the brightest object in the north eastern sky, and its distinctive red colour makes it easy to spot. Mars is rising around 8:00 pm (local daylight saving time), and is at its highest around 1 am.
Mars was at opposition on March 4, when it was biggest and brightest as seen from Earth. Sadly, this is a poor opposition and Mars will be fairly small in modest telescopes. Even so, you should be still able to see the polar caps, so still have a go if you have a telescope.
Saturn is above the north-eastern horizon, not far from the bright star Spica. Saturn is high enough in the northern sky in the early morning for telescopic observation, but is rising about 11:00 pm local daylight saving time.
Mercury is lost in twilight.
Evening sky on Wednesday March 14 looking west as seen from Adelaide at 8:00 pm local daylight saving time in South Australia showing Venus and Jupiter are at their closest. The insets shows the appearance of Venus seen telescopically at this time. Similar views will be seen elsewhere at the equivalent local time (click to embiggen)
Bright white Venus is readily visible in the evening western twilight sky from around half an hour after sunset for somewhat over an hour and a half.
Venus is in Pisces this week and continues to come closer to Jupiter. The pair are quite easy to see together and are closest on the 14th.
In the evening Jupiter is readily visible in the northern-western sky, from about twilight. Telescopic observation of Jupiter is now very difficult.
However, Jupiter is still a great binocular object. Jupiter is visible until around 10 pm local daylight saving time.
The star Omicron Scorpii is occulted by the Moon on the 13th.
With Mars at opposition and Saturn rising, there are lots of interesting things in the sky to view with a telescope. 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.
