Morning  sky on Tuesday March 21 looking east as seen from Adelaide at 5:52 ACDST (90 minutes before sunrise). Saturn is high above the horizon and the waning Moon is just below it.

The inset shows the telescopic view of Saturn at this time. Similar views will be seen elsewhere in Australia at the equivalent local time (90 minutes before sunrise). (click to embiggen).

 Saturn rises higher in darker morning skies this week. Saturn is now high enough above eastern horizon to see easily and is now a good telescopic target. It continues to climb into darker skies as the week progresses. It is within binocular distance of the Triffid and Lagoon nebula, however, the proximity of the waning Moon, closest on the 21st, makes viwing these nebular difficult.

The constellation of Scorpio is a good guide to locating Saturn. The distinctive curl of Scorpio is easy to see above the eastern horizon, locate the bright red star, Antares, and the look below that towards the horizon, the next bright object is Saturn.

Mercury is  lost in the twilight.

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.
