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.
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.
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.
