Thursday July 22 to Thursday July 29

The Full Moon is Saturday, July 24.  Mercury is lost to view. Venus is readily visible in the evening twilight and is leaving Mars behind as it approaches the bright star Regulus. Venus is closest to Regulus on the 22nd. Saturn and Jupiter are visible late in the evening sky and are visited by the Noon on the 24th-26th. Southern Delta Aquarids meteor shower peaks 29th-30th.

The Full Moon is Saturday, July 24.

Evening sky looking east from Adelaide at 11 pm local time in South Australia. The starburst marks the radiant  (the point where the meteors appear to originate from) of the Southern Delta Aquariids. Similar views will be seen elsewhere at the equivalent local time (click to embiggen).

The Southern Delta-Aquarids meteor shower runs from from 12 July to 23rd August, peaking on Thurday July 29 to 30. The number of meteors you will see depends on how high the radiant is above the horizon, and how dark your sky is. This shower is fairly faint, with the highest rate of around a meteor every 7 minutes. This year the shower occurs when the Moon is close to the radiant so lower rates will be seen than usual.

At 11 pm, face east, and look  towards Jupiter (the brightest object above the eastern horizon). The radiant is just below Jupiter. This meteor shower should be visible from 10.00 pm until dawn. However, after Moon rise the rates will fall off considerably.

Mercury is lost in the twilight.

Venus is visible in the late twilight.  I have been able to see Venus from 15 minutes after sunset and it is easily seen 60 minutes after sunset.  Venus has passed Mars and closes in on the bright star Regulus, being closest on the 22nd

Mars is visible in the evening sky above the north-western horizon in the early evening. Mars is being left behind by Venus but like Venus is heading for Regulus.
   
Jupiter is now above the eastern horizon well before midnight. Saturn and Jupiter form a line in the sky, and the pair are visited by the Moon from the 24th to 26th. On the 25th the Moon is between Saturn and Jupiter. On the 26th the Moon is just below Jupiter.
 
 Saturn is now rising well around 8pm.  On the 24th The Moon is just above Saturn.
On the 25th the Moon is between Saturn and Jupiter.
