The Sky This Week - Thursday November 29 to Thursday December 6
The Last Quarter Moon is Friday, November 30.
Similar views will be seen elsewhere in Australia at the equivalent local time (60 minutes before sunrise)
Similar views will be seen throughout Australia at the equivalent local time (60 minutes after sunset, click to embiggen).
Comet 46P is rapidly brightening and is roughly magnitude 5.5 now, readily seen as a fuzzy blob in binoculars. It may become bright enough to (just) see with the unaided eye in late December. More details on how to see it, along with charts suitable for printing, are here.
Mira (omicron ceti), a star in the constellation of Cetus the whale, is a red giant that pulsates over a period of about 331 days and changes brightness from below naked eye visibility to a peak of round magnitude 2 (roughly as bright as gamma Crucis in the Southern Cross) in around 330 days. Mira will peak magnitude later this week, and may stay bright the rest of this month. Following a line drawn between Sirus and Rigel will bring you to Mira.
Venus has returned to the morning skies and is close to the crescent Moon on December 4..
Mercury is lost in the twilight .
Jupiter is lost in the twilight and will return to the morning sky mid December.
Mars is in Capricornius and is readily seen in the evening. Mars is now rapidly dimming and shrinking. When Sirius rises Mars is no longer the brightest object in the night sky aside from the Moon. In a telescope you may see a few features but viewing will be difficult. This week the "gibbous" shape of Mars will be obvious.
Saturn is low in the north-western evening sky in the early evening and is setting around 10:15 pm. Its closeness to the horizon means it is no longer a good telescopic target.
