The Sky This Week - Thursday January 9 to Thursday January 16
The Full Moon is Saturday, January 11. Penumbral lunar eclipse morning January 11.Venus is prominent in the evening sky visible well after the of twilight. Mars is visible in the morning twilight in the head of Scorpius the Scorpion close to some bright stars. The Red Giant star Betelgeuse in Orion is still dimming.
The Full Moon is Saturday, January 11. Penumbral lunar eclipse morning January 11 The Moon is at perigee when it is closest to the Earth on January the 14th.
Sky at 21:38 ACDST on Saturday, January 11(60 minutes after sunset)
looking west as seen from Adelaide. Venus is prominent in the sky. The inset shows the telescopic view at this time.
Similar views will be seen elsewhere in Australia 60 minutes after sunset, click to embiggen.
Morning sky at 5:08 ACDST facing east as seen from Adelaide on Saturday, January 11, 60 minutes before sunrise.
Mars is low above the horizon and is in the head of Scorpius the scorpion. It is close to the stars Omega 1 and 2 Scorpii on the 9th and 10th. The inset shows the telescopic view of Mars on the 10th (10mm eyepiece 6" reflector).
Similar views will be seen elsewhere in Australia at the equivalent local time. (60 minutes before sunrise, click to embiggen).
Evening sky looking north-east at 22:17 ACDST on Saturday, January 11 (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 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 is now even dimmer than last week, reportedly between magnitude 1.6-1.8, it is 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 make it more difficult to estimate Belegeuses brightness.
Evening sky looking west at 3:36 ACDST on Saturday, January 11.The penumbral lunar eclipse has just started.
This is a very poor eclipse, with The moon immersed in the Earth's outer shadow and only the faintest hint of darkening will be seen before the dawn. Western Australia has the best view if western Australians want to get up around 3 am for maximum eclipse.
Venus is prominent above the western horizon in the early evening sky. Venus is now readily seen up to 90 minutes after sunset.
Mercury is low in the evening twilight but will be difficult to see this month.
Jupiter is lost in the twilight glow but will enter the morning sky later this month.
Mars is visible in the morning twilight. It is in the head of the scorpion, Scorpius, this week. It is close to the stars Omega 1 and 2 Scorpii on the 9th and 10th.
Saturn is in conjunction with the Sun on the 14th and will not become visible until it enters the morning sky in February.
