The Sky This Week - Thursday November 2 to Thursday November 9

The Full Moon is Saturday, November 4. Jupiter is lost in the twilight.  Mercury climbs higher in the evening twilight and meets delta Scorpii on the 7th. Saturn is visible in the early evening in the heart of the Milky Way.  Venus is now very low in  the morning twilight while Mars rises higher.

The Full Moon is Saturday, November 4. The Moon is at perigee, when it is closest to Earth, on the 6th.

Evening sky on Tuesday November 7looking north-west as seen from Adelaide at 20:36 ACDST  (45 minutes after sunset). Mercury is low above the horizon close to the star delta Scorpii.

Similar views will be seen elsewhere in Australia at the equivalent local time (45 minutes after sunset). (click to embiggen).

Mercury is setting in early evening and is above the western horizon in the twilight. Mercury is becoming more prominent, and is well worth watching as it rises into the evening sky, heading towards the head of Scorpius the scorpion. On the 7th, Mercury is close to the moderately bright star delta Scorpii in the head of the scorpion. Thi is the first of an interesting series of encounters over the coming weeks.

Jupiter is lost in the twilight.

Evening sky on Saturday November 4 looking west as seen from Adelaide at 21:22 ACDST, 90 minutes after sunset.

Similar views will be seen elsewhere in Australia at the equivalent local time. (90 minutes after sunset, click to embiggen).

Saturn is visible in the early evening setting around 11:00 pm local time. Saturn is has a very limited window as a  telescopic target from 9:30 pm daylight saving time until around  10:00 pm daylight saving time.

Although reasonably high in the early evening sky, Saturn continues to sink into the western evening skies as the week progresses.  Saturn's rings are visible even in small telescopes and are always good to view.

The constellation of Scorpio is a good guide to locating Saturn. The distinctive curl of Scorpio is easy to see above the north-western horizon, locate the bright red star, Antares, and the look to the left of  that and slightly above, the next bright object is Saturn.

Morning sky on  Saturday November 4 looking east as seen from Adelaide at 5:44 ACDST (30 minutes before sunrise). Venus is bright just above the horizon and forms a line with Mars.

 Similar views will be seen throughout Australia at the equivalent local time (that is 30 minutes before sunrise, click to embiggen).

Venus  is lowering in the morning sky. This week Venus forms a line with  Mars. It is becoming much harder to see Venus in the twilight, and you will need a clear unobstructed horizon to see the Venus low in the twilight. 

 Mars is climbing higher the twilight, and is now reasonably visible in the twilight.
