The Sky This Week - ThursdayApril 13 to Thursday April 20
The Last Quarter Moon is Wednesday April 18. Mars is low in the twilight. Jupiter
and
the bright star Spica
are
close in the late evening
skies, with Jupiter just past opposition.
Saturn is low in the late evening
sky and is close to the Moon on the16th. Venus climbs higher in the morning sky
The Last Quarter Moon is Wednesday April 18. The Moon is at apogee, when it is furthest from the Earth, on the 15th.
Evening sky on Saturday April 15 looking west as seen from Adelaide
at 18:47 ACST (60 minutes after sunset). Mars is low above the horizon,
below
Aldebaran and close to the Pleiades.
Similar views will be seen throughout Australia at the equivalent local time (that is 60 minutes after local sunset, click to embiggen).
Mercury is lost in twilight.
Mars is in the western evening skies in Taurus It is is low in the dusk sky, but is the brightest object above the western horizon low in the late twilight below Aldebaran. Over the week Mars comes close to the Pleiades cluster, you will need a clear, unobscured level horizon to see this though.
Evening sky on Saturday April 15 looking east as seen from
Adelaide at 19:16 ACST (90 minutes after sunset). Jupiter is above the horizon close to
the bright star Spica. The inset shows the telescopic
view of Jupiter at 20:06 ACST on the 15th with Europa appearing from occultation.
Similar views will be seen elsewhere in Australia at the equivalent local time. that is 90 minutes after local sunset, click to embiggen).
Jupiter is rising at dusk and is now reasonably high above the horizon in the early evening this week. It is close to the bright star Spica, the brightest star in the constellation of Virgo.
Opposition, when Jupiter is biggest and brightest as seen from Earth, was on the 8th. Jupiter is rising as the sun sets and is visible all night long. Jupiter is a good telescopic target from around 8 pm on, and the dance of its Moons is visible even in binoculars. The following Jupiter events are in AEST.
Evening sky on Saturday April 15 looking east as seen from
Adelaide at 23:00 ACST. Saturn is reasonably high above the horizon with the Moon nearby.
The inset shows the telescopic view of Saturn at this time. Similar views will be seen elsewhere in Australia at the equivalent local time. (click to embiggen).
Saturn is now visible in the late evening skies this week. Saturn is only a good telescopic target from midnight on. It continues to climb into the evening skys as the week progresses. It is within binocular distance of the Triffid and Lagoon nebula, although the closeness of the Moon this week will wash them out..
The constellation of Scorpio is a good guide to locating Saturn. The distinctive curl of Scorpio is easy to see above the north-eastern horizon, locate the bright red star, Antares, and the look below that towards the horizon, the next bright object is Saturn.
Morning sky on Saturday April 8 looking east as seen from Adelaide
at 5:44 ACST (60 minutes before sunrise). The inset shows the telescopic view of Venus at
this time.
Similar views will be seen throughout Australia at the equivalent local time (that is 60 minutes before sunrise, click to embiggen).
Venus climbs higher in the morning sky and is visible in telescopes as a thin crescent.
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.

Hi Ian, Will we get a decent view of Asteroid 2014 JO25 that will be making a close approach to Earth on April 19th?

G'Day Chris, we won't see the closest approach, that is NH only, but we can see it on the 20th under reasonably good conditions. http://astroblogger.blogspot.com.au/2017/04/seeing-asteroid-2014-j025-from.html
