Sky This Week - Thursday April 2 to Thursday April 9
The Full Moon is Wednesday, April 8. This is a perigee Syzygy Moon, the closest this year. Daylight savings ends on the 5th. Venus is prominent in the evening sky well after twilight and is in the Pleiades on the 3rd and 4th. Four bright planets are visible in the morning skies. Jupiter dominates the morning skies as Mars leaves Saturn behind. Mercury is visible below the trio. The Red Giant star Betelgeuse in Orion is still dim but is brightening.
The Full Moon is Wednesday, April 8. This is a perigee Syzygy Moon, where the full moon occurs at perigee, when it is closest to the Earth. This is the closest perigee Syzygy Moon this year. Daylight savings ends on the 5th.
Sky at 20:02 ACDST on Friday April 3 (60 minutes after sunset)
looking west as seen from Adelaide. Venus is prominent in the sky and on top of the iconic Pleiades cluster. The inset shows the binocular view of Venus and the Pleiades at this time.
Venus is a distinct "half Moon" shape in even small telescopes.
Similar views will be seen elsewhere in Australia 60 minutes after sunset, click to embiggen.
Morning sky at 6:07 ACDST (90 minutes minutes before sunrise)
facing east as seen from Adelaide on Saturday, April 4.
Four bright planets are dominating the morning skies. Jupiter, Saturn and Mars with Mercury is bright below.
Similar views will be seen elsewhere in Australia at the equivalent local time (90 minutes before sunrise).
Looking north-east after Full Moon on Wednesday, April 8 at 22:00
ACST (strictly Full Moon is at 13:00 ACST and Perigee at 4:00). The
Full Moon is a perigee
Moon when the Full Moon is closest to the Earth. This is the closest perigee Syzygy Moon this year. Don't look just at
moon rise as the horizon illusion
will make the Moon look bigger than it is, wait until it is a decent
way above the horizon. The size contrast will be best when comparing to
the October 31/November 1 apogee Moon.
A full Moon at perigee has been called a "Super Moon", this is not an astronomical term (the astronomical term is perigee syzygy, but that doesn't trip off the tongue so nicely), but an astrological one first coined in 1979 (see here).
Still, it is a good excuse to get people out and looking at the Moon.
Evening sky looking north-west at 20:30 ACDST on Saturday, April 4. (90 minutes after sunset). Similar views will be seen elsewhere in Australia at the equivalent local time. Orion is readily visible. Betelgeuse is the bright red star to the right of the "saucepan" of Orion.
Betelgeuse continues brightening, so keep watching this iconic star.
Betelgeuse is a red giant star which forms a distinctive part of the Constellation of Orion. It is a variable star, with small fluctuations in brightness not visible to the casual observer.
Betelgeuse had dimmed substantially and reached a 50 record minimum of around magnitude 1.6, but is now brightening again and is about magnitude 1 around the brightness of magnitude 1 Aldebaran, the next brightest star just to the west of (below) Betelgeuse. Keep an eye on this historic dimming and re-brightening event, observing hints and stars for magnitude estimation are given here. The waxing moon will interfere with estimates of Betelgeuses' brightness towards the end of the week.
Venus is prominent above the western horizon in the early evening sky. Venus is now readily seen up to 90 minutes after sunset. Venus will come closer to the beautiful Pleiades cluster early in the week, and will pass through it on the 3rd and 4th.
Four bright planets grace the morning sky..
Mercury is at its highest in the morning sky and bright. After this week it will begin to sink again
Mars is visible high in the morning sky. Mars is leaving the pair of Saturn and Jupiter behind.
Jupiter climbs higher in the morning sky, moving away from Mars. Jupiter and Saturn stay around a hand-span apart during the week.
Saturn climbs higher in the morning sky below Jupiter drawing away from Mars

Tuesday March10 was a perigee full Moon. Strictly Full Moon was at 4:18 ACDST and perigee was at 17:00 ACDST. The Full Moon is a perigee Moon when the Full Moon is closest to the Earth.
I captured the images above with my Xperia Mobile phone (1/4000th second exposure ASA 800) and my 4" Newtonian with 25 mm Plossl lens. The comparison image is the September 14 apogee Moon taken under the same conditions. The row below are the stellarium simulations. The simulations are rotated a bit compared to the telescope images due to the camera orientation, but the images are otherwise spot on.

Perigee ("super") Full Moon March 10, 2020.
|  |
| Full Moon March 10 22:00 AEDST, 6 hours after Perigee. Click to embiggen. | Full Moon November 1 02:00, apogee -20h. |
Tuesday March10 is a perigee full Moon. Strictly Full Moon is at 4:18 ACDST and perigee is at 17:00 ACDST. The Full Moon is a perigee Moon when the Full Moon is closest to the Earth. This is not as good as the April 8 perigee Moon but is still very good.
As perigee is when the moon is blow the horizon, at moon rise the Moon is receding from Earth but still larger ten at the moment of full Moon at around 4 am.
However, don't look just at moon rise as the horizon illusion will make the Moon look bigger than it is, wait until it is a decent way above the horizon. anywhere between 9 am to 11 am the Moon will still be a decent diameter. The location of the Moon to the north-east will be obvious.
You won't see much of a difference if you compare it with them memory of last months full Moon. You will need to either remember the apogee Moon of September 13/14 or wait until the October 31/November 1 apogee Moon for the best size contrast.
A full Moon at perigee has been called a "Super Moon", this is not an astronomical term (the astronomical term is perigee syzygy, but that doesn't trip off the tongue so nicely), but an astrological one first coined in 1979 (see here).
Still, it is a good excuse to get people out and looking at the Moon. A guide to photographing the Perigee Full Moon is here.

Venus close to Uranus (8-9 March, 2020)
Similar views will be seen elsewhere in Australia 60 minutes after sunset, click to embiggen.
On the 8th and 9th Venus is close to Uranus. Close in this context being around two finger-widths away. While in theory Unaus is bright enough to be seen with the unaided eye (magnitude 5.8), its closeness to the horizon, best visibility at nautical twilight (and hour after sunset) and the brightness of Venus, Uranus will be effectively visible only in binoculars.
Unfortunately stellarium washes out the stars when I try and make a higher powered spotters map, so I made a black and white printable map, this shows the track of Venus and Urans from the 7th to 10.
The circle is the approximate filed of view of 10x50 binoculars and the Pleiades (also seen in the stellarium chart) are at the upper right.
The chart is in the same orientation as the spotters charts,stars down to magnitude 11 are shown. The circle is the approximate filed of view of 10x50 binoculars. This shows the track of Venus and Uranus from the 7th to 10.
A scale line and compass direction is also shown. Use in conjunction with a red torch to preserve your night sight.

The Sky This Week - Thursday March 5 to Thursday March 12
The Full Moon is Tuesday, March 10. This is a Perigee Moon. Venus is prominent in the evening sky well after twilight on the 8th and 9th Venus is close to Uranus. By midweek four bright planets will be visible in the morning skies. Mars heads towards Jupiter with Saturn below. Mercury is low to the horizon. The Red Giant star Betelgeuse in Orion is still dim but seems to be brightening.
The Full Moon is Tuesday, March 10. This is a Perigee Moon, full Moon is 4am and Perigee is 4pm, but the Moon will still be big when it rises. Next months perigee Moon is better but this is still a good one.
Sky at 20:39 ACDST on Sunday, March 8 (60 minutes after sunset)
looking west as seen from Adelaide. Venus is prominent in the sky. At this time it is closest to the dim planet Uranus. The inset shows the approximate binocular view of Venus and Uranus at this time.
Similar views will be seen elsewhere in Australia 60 minutes after sunset, click to embiggen.
Morning sky at 6:12 ACDST (60 minutes minutes before sunrise)
facing east as seen from Adelaide on Saturday, March 7.
Four bright planets are dominating the morning skies. Mars is at its closest to the globular cluster M22 at this time. The inset is the telescopic view through a 24 mm eyepiece of a 4" Newtonian. Jupiter is well above the horizon and Saturn appears below it.
Similar views will be seen elsewhere in Australia at the equivalent local time (60 minutes minutes before sunrise) .
Looking north-east after Full Moon on Tuesday, 10 February at 23:00 ACDST (strictly Full Moon is at 4:00 ACDST and Perigee at 16:00). The Full Moon is a perigee Moon when the Full Moon is closest to the Earth. This is not as good as the April 8 perigee Moon but is still very good. Don't look just at moon rise as the horizon illusion will make the Moon look bigger than it is, wait until it is a decent way above the horizon. The size contrast will be best when comparing to the October 31/November 1 apogee Moon.
A full Moon at perigee has been called a "Super Moon", this is not an astronomical term (the astronomical term is perigee syzygy, but that doesn't trip off the tongue so nicely), but an astrological one first coined in 1979 (see here).
Still, it is a good excuse to get people out and looking at the Moon.
Evening sky looking north at 21:09 ACDST on Saturday, Saturday, March 7. (90 minutes after sunset). Similar views will be seen elsewhere in Australia at the equivalent local time. Orion is readily visible. Betelgeuse is the bright red star below the "saucepan" of Orion. Red Aldebaran is almost the same height above the horizon as red Betelgeuse, making brightness comparisons easy.
Betelgeuse has begun brightening again , so keep watching this iconic star.
Betelgeuse is a red giant star which forms a distinctive part of the Constellation of Orion. It is a variable star, with small fluctuations in brightness not visible to the casual observer.
Betelgeuse has dimmed substantially and reached a minimum of around magnitude 1.6, but is now brightening again and is about magnitude 1.4. It is still visibly dimmer than magnitude 1 Aldebaran and roughly as bright as Bellatrix. The next brightest star just to the north of Betelgeuse. Keep an eye on this historic dimming event, observing hints and stars for magnitude estimation are given here. The waxing/full moon will interfere with estimates of Betelgeuses' brightness during the week.
Venus is prominent above the western horizon in the early evening sky. Venus is now readily seen up to 90 minutes after sunset. Venus is close to dim Uranus on the 8th and the 9th. Although too dim to be seen with the unaided eye in the twilight, Uranus should be readily visible in binoculars, although Venuses glare may interfere.
Four bright planets grace the morning sky.
Mercury returns to the morning sky and gets visibly brighter during the week.
Mars is visible high in the morning sky. Mars comes closer to Jupiter during the week.
Jupiter climbs higher in the morning sky.
Saturn climbs higher in the morning sky below Jupiter.
