February skies 2026

Northern sky on Friday, February 27  as seen from Adelaide at 21:22 ACDST (90 minutes after sunset, click to embiggen).  Jupiter is close to the nearly full Moon, forming a narrow triangle with Castor and Pollux and a broad triangle with the bright stars Procyon and Betelgeuse. 
 

The inset is the telescopic view Jupiter at this time.  

    

 
 
 
 
Similar views will be seen from the rest of Australia at roughly the equivalent local time (90 minutes after sunset).

Sky looking North-west on Tuesday February 24 as seen from Adelaide at 20:56 ACDST (60 minutes after sunset, click to embiggen). 

The First Quarter Moon is clearly visible above the horizon close to he Pleiades cluster. the Lunar X and V may bee seen in a telescope or strong binoculars. The insets show the telescopic and binocular views at this time. 

 

 

 

 

Similar views will be seen from the rest of Australia at roughly the equivalent local time (60 minutes after sunset). 

Stars:

North western sky as seen from Adelaide at 21:41 ACDST (90 minutes after sunset). Similar views will been seen elsewhere in Australia 90 minutes after sunset.

Theta Carina is indicated by the circle, The inset is the binocular view of the the Southern Pleiades and Theta Carina  at this time (click to embiggen)


February nights see the summer constellations of Taurus the Bull, Orion the Hunter and Canis major (Orion’s hunting dog) slip into the north-western sky.


Orion is still visible,  as are the Pleiades, a close grouping of six stars.   A line drawn westward through Betelgeuse, the red star that forms the shoulder of Orion, and Aldebaran brings you to the Pleiades.

Although faint, the Pleiades is pretty to the unaided eye, and delightful in binoculars. If you’re fortunate enough to have a decent telescope, you’ll be able to see a hint of the nebulous cloud that makes photographs of this cluster an astronomical icon. 


The Pleiades is also known as the Seven Sisters in European culture.  Interestingly, many Indigenous Australian groups also saw the cluster as women. The Boorong people of north-western Victoria called it Larnankurrk and described it as a group of women watching Kulkunbulla (the two dancing youths represented by the Saucepan of Orion’s belt).   However, the people of the Lake Albert area saw the Pleiades as a clutch of turkey eggs.


In February, you can also see a constellation called the “Southern Pleiades” (it’s only visible in the southern hemisphere).  It’s a lot less obvious to the unaided eye than the Pleiades themselves, but is truly beautiful in binoculars or a small telescope.  It’s made up of a cluster of stars around theta Carina, which also glories in the name Vathorz Posterior.

To find this small gem, look up from Acrux, the brightest star in the Southern Cross. The second bright star you come to is surrounded by a halo of dim stars, this is the Southern Pleiades. 
You can easily see the Pleiades and the Southern Pleiades from around an hour after sunset as they emerge from the twilight.


 As the night progresses the Pleiades sink into the west. In contrast, the Southern Pleiades rise higher above the southern horizon as February progresses but they will become harder to see due to moonlight.  


Mira:

 

North western sky as seen from Adelaide at 21:41 ACDST (90 minutes after sunset). Similar views will been seen elsewhere in Australia 90 minutes after sunset. The variable star Mira is above the western horizon and indicated by the circle. The inset is the binocular view of the Mira and the two obvious stars Zeta and Chi Ceti at this time (click to embiggen)

 
The variable star Mira (omicron Ceti) should start to brighten in February, rising from below unaided eye visibility to around magnitude 4 before peaking in March at around magnitude 3. It will be seen low above the western horizon when the sky is fully dark.

Occultation Pleiades 30 July 2024.

Morning sky on Tuesday, July 30 as seen from Adelaide at 5:10 ACST, (click to embiggen). The moon is just about to cover the star Celaeno in the Pleiades. The inset is the binocular view of the moon at this time (click to embiggen).
Morning sky on Tuesday, July 3 as seen from Melbourne at 6:05 AEST, (click to embiggen). The moon is just about to cover the star Taygeta in the Pleiades. The inset is the binocular view of the moon at this time (click to embiggen). Evening sky on Tuesday, July 3 as seen from Perth at 3:03 AWST, (click to embiggen). The moon is just about to cover the star Celaeno in the Pleiades. The inset is the binocular view of the moon at this time.  (click to embiggen).

On the early morning 30th the waning cresent Moon will pass over (occult) some bright stars in the iconic Pleiades cluster. From western Australia and central Australia the most stars will be covered. Eastern states see only one bright star covered.

While potentially visible to the unaided eye, this is best seen with binoculars or a telescope. While a waning crescent, the Moon is still bright enough to wash out all but the brightest members of the Pleiades. Fortunately, for most of Australia at least one of the bright stars in the cluster, Taygeta (19 Tau, mag 4.3) are covered. Perth and the west coast gets the best view, with Darwin, Alice Springs (and places between) and Adelaide being next best. The east coast is in twilight when the moon moves off the Pleiades.

Timings for the covering of Celaeno (16 Tau), Taygeta (19 Tau) and Sterope (21 Tau) are give below for selected cities.  Similar views will be seen at nearby locations (e.g. Fremantle and Perth, Alice Springs and Darwin)

* Occurs in twilight

It’s best to set up around 30 minutes before the occultation so you can get oriented in the sky and don’t miss the beginning while fussing with equipment.
