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 1.5-1.6, 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 waning moon will be out of the way making it easier to estimate Belegeuses' brightness.
Venus is prominent above the western horizon in the early evening sky. Venus is now readily seen up to 90 minutes after sunset. 0n the 28th Venus is close to the crescent Moon.
Mercury is difficult to observe low in the twilight. It is close to the thin crescent Moon on the 26th.
Jupiter climbs higher in the morning twilight.
Mars is visible high in the morning twilight. It is near the scorpion, Scorpius, this week. It is close to the bright red star Antares (the rival of Mars) at the start of the week.
Saturn was in conjunction with the Sun on the 14th and will not become visible until it enters the morning sky in February.
