The Sky This Week - Thursday January 17 to Thursday January 24

The Full Moon is Monday, January 21. This is a perigee full Moon. Mars is visible low in the evening skies. Venus is bright in the morning sky and Jupiter below is closing in on it. The pair are closest on the 23rd. Saturn climbs higher in the morning sky.

The Full Moon is Monday, January 21. This is a perigee full Moon, also called a "super Moon" (although perigee is technically the next day, the full Moon of February  19 is closer to perigee). There is also a total Lunar eclipse, but this will not be seen in Australia.

What can you expect to see with the "Super Moon" of  January 21 ?

Not much really, unless you are a regular observer of the Moon, have good visual acuity and a good memory.

The problem is, while the Moon is close this time around, it doesn't actually translate into something you can easily see with your unaided eye. Mondays Full Moon will be around 14% larger and 30% brighter than September's apogee Full Moon.So unless you have a good memory, you won't wee much (but it will be a good opportunity to photograph the full Moon, then again in September and compare the images.

 Venus climbs higher in the morning skies and Jupiter is heading towards it. The pair are closest on the 23rd.

Mercury  is lost in the twilight

Jupiter  climbs higher in the morning sky heading towards Venus. The pair are closest on the 23rd.


Mars is in Pisces and is readily seen as the brightest object in the western evening sky. Mars sets just before midnight.

Saturn is climbs higher in the morning sky although it is still quite  low.
