The Sky This Week - Thursday April 19 to Thursday April 26
The First Quarter Moon is Monday, April 23. The Moon is at perigee, when it is closest to the Earth, on the 21st.
Similar views will be seen throughout Australia at the equivalent local time (30 minutes after sunset, click to embiggen).
Venus is rising higher in the twilight. While is is now much easier to see, you will still need a flat unobscured horizon to see it at its best. Venus is visible to the unaided eye from 15 minutes after sunset, easy to see 30 minutes after sunset and can potentially be viewed as late as an hour after sunset if you have a flat, unobstructed horizon.
The inset is a simulated telescopic view of Jupiter and its moons at 3:00 ACST on the 22nd, with Europa and its shadow transiting the face of Jupiter.

Venus is now sufficiently high in the evening twilight to be readily visible above the horizon if there are not too many trees or buildings in the way. It is now over a hand-span above the horizon 30 minutes after sunset. It is bright enough to be visible 15 minutes after sunset and easy to see 30 minutes after sunset and can potentially be viewed as late as an hour after sunset if you have a flat, unobstructed horizon. On the 19th the thin crescent Moon is near Venus.
Mercury has returned to the morning sky, and now is in an excellent position for observation. Mercury is the brightest object closest to the eastern horizon.
Jupiter is rising in the early evening, and is now a good telescopic object in the late evening. There are some good Jovian Moon events this week.
Mars is in Sagittarius the archer and is now rising in the late evening. Mars is moving away from Saturn although the pair are still obvious together. Mars is brightening ahead of opposition later this year.
Saturn has entered the evening sky, although telescopically it is still best in the morning sky. It is within binocular range of several attractive clusters and nebula. It is close to the bright globular cluster M22 and the pair are visible in binoculars and wide field telescope eyepieces.
