The Sky This Week - Thursday June 11 to Thursday June 18
The New Moon is Wednesday June 17. The crescent Moon occults Uranus June 12.
On the morning of Friday 12 June Uranus is occulted by the Moon as seen from southern Australia (basically anywhere south of Townsville).
Southern Australia has the best views of ingress and egress. This is very much a binocular/telescope event, and only moderately sized telescopes or larger will show Uranus as more than a tiny dot, but it is interesting none the less. More details, charts and timings for a variety of cities are here.
Mercury climbs higher in the morning skies this week, on the 15th it is close to the crescent Moon. In the coming weeks Mercury will rise higher in the sky, and has some interesting encounters with the Hyades and Aldebaran.
Venus is close to the Beehive cluster on the 14th.
Jupiter is the brightest object above the north-western horizon once Venus has set. Insets show the telescopic views of Venus and Jupiter at this time. Similar views will be seen elsewhere in Australia at the equivalent local time. (click to embiggen).
Mars is lost in the twilight.
Venus is easy to see above the western horizon in the twilight. At nautical twilight, an hour after sunset, it is around two hand-spans above the horizon, and still visible at astronomical twilight. Venus is a distinct "half Moon" shape in even small telescopes.
At the start of the week Venus. Jupiter and the star Regulus in Leo forms a line. Venus draws closer to Jupiter during the week, heading for a a very close meeting at the end of the month.
On the 14th, Venus is within binocular distance of the faint but beautiful beehive cluster, it is actually on the outer edges of the cluster at this time, but Venus's brilliance may obscure most of the members of the cluster.
Jupiter is easily seen in the evening sky. It is the brightest object above the northern horizon when twilight ends, and continues into the north-western sky as the night goes on. It is between the bright star Regulus in the sickle of Leo (this forms the head of the constellation of the Lion) and Pollux in Cancer. It is also not far from the rather nice Beehive cluster in Cancer, and looks very good in binoculars. Jupiter and Venus are coming closer.
Jupiter is visible in the early evening, seting just after 9 pm, and is high enough for telescopic observation once twilight is over. Jupiter's Moons will be putting on a good display in both binoculars and small telescopes.
Saturn is now easily visible from 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 close to its head, is very nice indeed.
While Saturn is readily visible from around 19:00, it is best for telescope observation from around 20:00 into the early morning hours.
There are lots of interesting things in the sky to view with a telescope. Especially with Jupiter, Venus and Saturn in the sky. 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.
