The Sky This Week - Thursday November 12 to Thursday November 19
The First Quarter Moon is Thursday November 19.
Mercury is lost in the twilight.
Saturn is visible at twilight in the head of the constellation of the Scorpion not far from the bright red star Antares. The sight of the distinctive back to front "question mark" constellation of the Scorpion above the horizon, with bright Saturn in its head, is very nice indeed. However, this is the last week to see Saturn before it disappears into the twilight glow.
Saturn is close to the double star nu Scorpii at the start of the week. It moves away from nu Scorpii as the week progresses. Saturn is joined by the crescent Moon on the 13th, but the pair will be difficult to see in the twilight without a clear, level horizon. After this, Saturn is lost to view until December, when it appears in the morning sky.
Jupiter rises higher in the morning skies and is now easy to see in the dark of early twilight.
Mars is higher in the morning skies and is visible in the early twilight.
Venus is easy to see in the morning twilight. It is a distinct "half Moon" shape and impressive in a small telescope.
Jupiter, Mars, Venus and the bright stars Regulus form a line in the sky this week. Venus starts the week close to Mars.
Morning sky looking north-east as seen from Adelaide at 5:00 am local daylight saving time on Wednesday November 18 showing Jupiter, Mars and Venus near Leo, with the Leonid Meteor shower radiant indicated with a starburst. Similar views will be seen elsewhere at the equivalent local time. Click to embiggen.
On the morning of Wednesday November 18 the Leonid Meteor shower peaks (from the point of view of Australians, that's 17 November UT), with the best time being between 3-4 am.
This is a not a particularly good Leonid year. Very few meteors will be visible (maybe oneto two per hour). You can use the Meteor Flux Estimator to get a prediction for your location. Use the 13 Leonids option and don't forget to set the year to 2015.
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.
