Morning sky on Wednesday, July 29 showing the northern sky as seen from Adelaide at 3:00 am ACST after Moonset when the radiant is still high and meteor rates are best. The radiant of the Southern delta Aquariids is shown with a starburst.
The Southern Delta-Aquariids meteor shower runs from 12 July to 23rd August, peaking on Wednesday, July 29. 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 4 minutes.

Comet C/2020 F3 NEOWISE has been entrancing viewers in the northern hemisphere, and from July 28 we get to see it. Sadly by the time it enters our skies, it will have faded to possibly magnitude 4, around as bright as epsilon Crucis (the fifth brightest star in the Southern Cross). It will be difficult to make out in the twilight and may require binoculars to see. It will look like a fuzzy dot and a small tail might be visible if we are lucky. The chart shows the position of NEOWISE on the 28th (lower circle) and 30th (upper).

Four bright planets grace the morning sky (Five, although Mercury is hard to see).
Pluto Neptune and Uranus are also part of this line-up, but unable to be seen with the unaided eye.
Mercury is difficult to see low in the morning twilight.
Venus is below the bright red Aldebaran (the eye of the Bull). Venus is heading towards the tip of the horns of the Bull.
Mars is visible high in the morning sky to the north, east of Jupiter and Saturn. It enters the evening sky shortly before midnight but is still low to the horizon.
Jupiter is lowering in the morning sky and now can be readily seen in the early evening sky. Jupiter and Saturn stay around a hand-span apart during the week. Jupiter was at opposition, when it was biggest and brightest as seen from Earth, on the 14th, but is still an excellent sight.
Saturn is also lowering in the morning sky near Jupiter drawing away from Mars. It too is now visible in the early evening skies. Saturn was at opposition, when it was biggest and brightest as seen from Earth, on the 21st, but is still an excellent sight.
