The Sky This Week - Thursday October 4 to Thursday October 11
The Last Quarter Moon is Monday October 8. Mars enters the head of the Scorpion. Saturn, Mercury and the
star Spica form a triangle low in the western evening sky with Mercury being closest to Saturn on the 5th. In the morning skies Jupiter and Venus can be
readily seen amongst some beautiful
constellations. On the morning of the 6th Jupiter is occulted by the Moon.
Morning sky on Saturday October 6 looking north as seen from Adelaide at 5:00 am local
time in South Australia. The Moon is about to graze Jupiter. Jupiter is below the Hyades and makes a long triangle with the red stars Betelgeuse and Aldebaran. Venus (off right not in this image) is very close to the bright star Regulus. Similar views will be seen elsewhere at the equivalent local time
(click to embiggen).
The Last Quarter Moon is Monday October 8.
Jupiter is easily seen in the early morning sky. Jupiter is below the Hyades and stays in roughly the same position for most of the week. Jupiter is not far from the waning Moon on the 5th.
On the 6th Jupiter is occulted by the Moon as seen from the South-eastern states.This occurs in daylight, but can still be viewed in telescopes and binoculars if care is used to not accidentally point at the Sun.
Adelaide sees a near miss at 7:30 am, Canberra sees a near miss at 8:11 am, Melbourne sees a graze at 08:05 am, Hobart sees an occultation start at 7:42 am, and Pert sees an occultation at 4:52 am.
Bright white Venus is still moderately high above the eastern horizon, but continues sinking lower over the week. Venus looks like a waxing Moon when seen through even a small telescope.
Jupiter, Aldebaran and the red star Betelgeuse in Orion form a long triangle in the sky. With the Pleiades cluster and the constellation of Orion close by, this is a beautiful morning sight.
Venus is in the constellation of Leo, it starts the week near the bright star Regulus but moves away over the rest of the week.
Evening sky looking west as seen
from Adelaide at 7:00 pm local time on Sunday September 30. Mars, Saturn and the bright star Spica
form a long triangle, with the Mercury close to Spica. Similar views will be seen
elsewhere at the equivalent local time. Click

Saturn is just above the north-western horizon, not far from the bright star Spica. Saturn is low in the twilight, which is not good for telescopic observation.
Saturn was at opposition, when it is biggest and brightest as seen from Earth, on the 16th of April. Now you only have a very short viewing time before Saturn is too low to observe, and telescopic views are even more limited. Saturn sets around 8:00 pm local time
Mercury is low in the twilight, on the 5th it is close to the Saturn.
Mercury, Saturn and the bright white star Spica from an attractive triangle in the evening sky, although you will need a low level horizon to see them at their best.
Mars starts the week in the constellation of Libra but soon moves into Scorpius. Mars is brightest object in the north-western sky, and its distinctive red colour makes it easy to spot. Mars sets shortly after 10:00 pm local time.
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.
Over the week, Mars moves closer towards the head of Scorpius the Scorpion. On the 10th and 11th it is in the head of the Scorpion, close to the bright star delta Scorpii
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.
