The Southern Delta Aquarid meteor shower will be best observed from July 28 to 31 and is estimated to peak before midnight and onwards on July 29/30. These are part of a complex of radiant in Aquarius, Capricornus and Piscis Austrinus, all of which combine with sporadic and early Perseid activity to provide a nice display of meteors in the last week of the month. The stream normally produces about 5-10 meteors/hour with overall activity of about 15 meteors/hour under good sky conditions. Unfortunately, the bright Moon will interfere the activity. Figures 2 & 2a show the position of the constellation Aquarius-the Water Bearer, where the radiant will originate.
Stargazers will be having a nice time watching the night sky with the famous Summer Triangle of the stars Vega, Deneb and Altair of the constellations Lyra, Aquila and Cygnus, respectively, being well placed in the eastern horizon as shown in Figures 1 & 1a. Also shown in Figure 1a are well known constellations like Ophiuchus -the Serpent Holder, Scorpius –the Scorpion and Sagittarius the Archer.
The Planet whereabouts…
From July 1 to July 31 at 4:00 A.M., a grand view of planets will be observed from the eastern towards the western horizon. Jupiter, Saturn, Neptune, Mars, Uranus and Venus will become very good targets for astrophotography as shown in Figures 4 to 6.
Figure 7 shows how to compare apparent magnitudes of celestial bodies such as planets and stars.
