July Supermoon 2023: The July full Moon is a supermoon, and is popularly known as the Buck Moon. It is the first supermoon of 2023, and reached full illumination in the skies at 7:39 am EDT (5:09 pm IST) on July 3. Sunset will occur in India at around 6-7 pm IST, because of which people will be able to see the supermoon a few hours after the Moon reaches full illumination. Also, the Moon will appear full through Tuesday night. 

A full Moon that appears slightly brighter and larger than a regular full Moon because it is located at perigee, the point in Moon's orbit  closest to Earth, is called a supermoon. The distance between the perigee and Earth is about 3,63,300 kilometres. 

Astrologer Richard Nolle coined the term "supermoon" in 1979. He used the word to describe either a new Moon or full Moon that occurs when the Moon is within 90 per cent of perigee. 

It is not possible to see a new Moon, except when it passes in front of the Sun. This is the reason why people usually associate a supermoon only with full Moons. Also, full supermoons are the biggest and brightest full Moons for the year. 

After the supermoon of July 3, three more supermoons will occur this year. 

Due to the gravitational influence of the Sun and other planets, the shape of the Moon's orbit changes over time. When the Moon is full, and at an extreme perigee, the satellite's angular radius and diameter appear slightly larger than they do at other full Moons. An extreme perigean full Moon is one in which the full Moon occurs precisely when the Moon is closest to Earth. 

When the full Moon is high in the sky and there are no lights around, the differences in ground illumination will appear indistinguishable to one's eyes. 

During an extreme perigean full Moon, high tides and low tides are more extreme compared to a perigean full Moon. This is because the Moon exerts a greater gravitational pull across Earth's diameter, compared to other days. 

Coasts may face problems due to perigean high tides because a storm surge may occur. 

In the 1930s, the Maine Farmers' Almanac began publishing Indian names for full Moons. 

The Algonquin tribes of what is now the north-eastern United States called the full Moon in June or July the Buck Moon. This Is because in early summer, the new antlers of buck deer push out of their foreheads in coatings of velvety fur. 

The full Moon is called the Thunder Moon because there are frequent thunderstorms in early summer.
