This evening the planet Venus, the bright evening star, reaches Greatest Elongation. That means the angular separation between the Sun and the planet Venus will be at maximum of 46 degrees, as observed from Earth. After this day the angular separation between the Sun and Venus starts decreasing
If observed through telescope, we can notice that Venus one half lit by reflected light from the Sun and the other half in dark. As the days progress, planet Venus will move from Half phase to Crescent phase, making the planet little more brighter.
Seen through the telescope the planet Venus will slowly increase in size, angular diameter, as the days pass. Now its around 24 seconds of arc and the planet will slowly increase to a diameter close to a minute of arc before reaching inferior conjunction in late October.
Venus is well placed for observations in the western evening sky through out this month.
This evening the red planet Mars will be 1° 57' NE of bright Venus.
Hope the skies will be clear...
