At the end of October it was ready to present an amazing view in the form of a ‘blue moon’ in its night sky, and to be exact, the proverbial phrase ‘Once in a Blue Moon’ will finally come under our gaze. The sky from the wonder. While a crucial element in the context of dramatic, niggling and scary stories, Blue Moon has long been an important part of attracting folk tales.

Then, on October 31, from 8.19 pm, the Blue Moon will appear in the night sky. Also, there are two full moons in October this year, of which the second moon is usually anointed as the Blue Moon. The first full moon occurred between October 1 and October 2, and the second full moon will occur in a few days.

In addition, a second full moon of this kind occurs every 30 months, while there will not be a full moon in February, said Arvind Paranpe of the Nehru Planetarium in Mumbai. The reason behind this phenomenon is that the lunar month has a length of 29 days, 12 hours 44 minutes 33 seconds and must occur on the first or second day of the first lunar month. There are only 28 days in February, which is why this month does not witness a bright view of a full moon.

Interestingly, the shape of the blue moon does not seem to be related to its color, because the blue moon rarely appears in all its glory. If everything happens, it is caused by dust and smoke particles contained in the earth’s atmosphere in the sky. These particles, which are more than 900 nanometers wide, can affect the scattering of red light in the atmosphere, which somehow makes the moon appear blue.

The blue moon sometimes occurs in the 30-day month that appeared on June 30, 2007, and the next will occur on September 30, 2050. Recently, the blue moon was seen on January 31, 2018 and will only be witnessed on March 31, 2023 and August 31, 2023. Whenever a Blue Moon occurs, the total number of full moons in that year changes to 13, which under normal circumstances would remain at 12.

In addition to these, the first full moon to occur earlier this month was called the ‘Harvest Moon’. This full moon shone until midnight, and in the past it helped farmers to harvest summer agricultural produce after midnight. Apparently, this happens while the Earth’s ellipse is turning into the smallest angle relative to the horizon, and eventually the Moon appears to have its brightest and brightest.
