On 31 October 2020, it is becoming a very rare coincidence. The first thing is that October 31 is the full moon. Sharad Purnima will also be celebrated on this day. After a long time it is becoming a coincidence that there are two full moon in the same month. It was also a full moon on October 1. The second thing is that 31 is also Halloween. On this day, for the first time in the sky, the moon is going to be seen in blue color i.e. Blue Moon.
Although the Blue Moon is an unusual astronomical phenomenon that is seen every two-three years, but the Blue Moon that appears in 2020 will be seen again in 2039, so this year’s Blue Moon is very special. According to NASA, the moon usually looks yellow and white during blue moon, but this time the moon will be different.
The year 1883 also gave people a chance to see the Blue Moon when the moon began to appear blue due to the dust dissolving in the air due to the eruption of the volcano Krakota, although it was not considered an astronomical event. Another thing to note here is that Blue Moon does not mean blue moon, but in case there are two full moon in a month, the second full moon is called Blue Moon. Blue Moon can be seen from 5: 45 pm on October 31 at 8:18 pm.
