Keeping in mind the location of the viewer in India, one needs to observe the east a few minutes post sunset while the moon remains above horizon.

The rise time for moon is different for different places. In Delhi it will be visible at 7.01 pm, in Ahmedabad 7.14 pm, in Bhopal 6.54 pm, in Dibrugarh at 5.46 pm, and in Kanyakumari at 6.36 pm.

In July 2, the first full moon of the month was noticed, and it is a rarity that the month will see yet another full month. This instance when the full moon is visible twice is known as “Blue Moon”.

Raghunandan Kumar who is the founder as well as founder secretary of the Planetary Society explained that usually one full moon can be noticed every month in a single calendar year.

Apart from these 12 full moons, every single calendar year comprises of an extra number of around 11 days, owing to the disparity between lunar and solar years. These extra numbers of days assemble together, and an additional full moon other than the usual 12 ones, can be noticed every two or three years.

The last Blue Moon was noticed in August 2012, and the next time it will be noticed will be in January 2018.

Although the name “Blue Moon,” observers should not be fooled, thinking that the moon will “actually” look blue.

National Aeronautics and Space Administration (NASA) explained in a report by abc NEWS that usually when the moon is dangling low, it appears red for the “same reason that sunsets are red.”

It added that the atmosphere is filled with aerosols, which are much tinier than the aerosols shot up by volcanoes, and these aerosols are the ones that disperse blue light, departing the red behind.

According to a report by CNN, one instance of this occurred in 1883 at the time when Krakatoa – an Indonesian volcano, exploded. It emitted a large quantity of ashes into the atmosphere making the moon grasp a cerulean tinge for many years. Post the enormous explosion; the volcanic remains triggered bright red sunsets and the moon to possess a bluish touch.
