Though the monsoon will still be active in September and we may expect a few showers, it is time to get ready for star gazing. The period soon after the rain can actually be very good for observations. The rain would have wash away the smog in the atmosphere; and the moist ground reduces the probability of dust being thrown into the atmosphere.

The autumnal equinox takes place on the 23rd at 7:24 IST. On this day the sun’s rays fall perpendicular to the axis of the Earth. This has led to the common misconception that on this day the duration of day and night are equal all over the Earth but that is not true. One can check this by noting down the rising and setting times of the Sun from the local newspapers.

The ‘equinox’ days for the four Indian metros are as follows: Delhi September 27; Kolkata September 28; Mumbai September 29; and Chennai October 02.
