Skywatchers: See full supermoon on December 3

Skywatchers: See full supermoon on December 3

The first and last "Supermoon" of 2017 will be visible in the sky this weekend.

Arvind Paranjpye, director of the Nehru Planetarium at Nehru Centre, Mumbai, told The Indian Express that the supermoon appears to be nearly 14 per cent larger and about 30 per cent brighter than the normal full moon, as seen from Earth. But that doesn't mean this weekend's supermoon won't be attractive - expect a full moon at least 7% bigger and 16% brighter than usual.

It'll be a site to see on Sunday night when the full moon comes out as it'll be our only Supermoon of 2017. For people of the Northern hemisphere, the December full moon is called as a cold moon. "As the moon goes round the Earth, its distance from the Earth keeps changing", he said.

A bright treat will greet skygazers Sunday night. This makes the full moon appear even larger and luminous due to its increased proximity to the planet.

To see the moon at its most vivid, it's best to catch a glimpse just after sun down.

Going to miss Sunday's supermoon? This effect is termed as "moon illusion".

A supermoon is also believed to have an impact on the Earth's waters.

Just to be clear, the supermoon is only the moon-there will be no eclipse and no colors. On the three dates marked, step out into the moonset or moonrise and look up for a trilogy of sky watching treats!

Bill Ingalls, a NASA photographer, says that those capturing the event through their smartphones have to focus on the correct light balance. "Then slide your finger up or down to darken or lighten the exposure".

What's the difference between a supermoon and a Blue Moon?

Do it near the horizon, and do it again away from the horizon. "It's a fun way to get involved in science".
