On November 19, the Moon was covered by the Earth’s shadow and we were able to witness a breathtaking and captivating sight of a partial lunar eclipse, which was also the last lunar eclipse of the year. A partial lunar eclipse occurs when the Earth comes between the Sun and the Moon, but not in a perfect line.

The partial lunar eclipse on November 19 has its own significance because it was the longest eclipse since the 15th Century, extending over six hours. The lunar eclipse, the last of 2021, was visible across different countries of the world including North America, South America, Europe, and parts of Asia, including India. The last time an eclipse this long occurred was on February 18, 1440.

According to sources, the eclipse began between 06.02 and 12.03 UTC (11.32 am to 5.33 pm IST) when the Sun, Earth, and Moon came into alignment, forming a partial lunar eclipse.

Why was this Eclipse so Long?

The November 19 partial lunar eclipse shattered records for the longest eclipse becoming longer than a total lunar eclipse. The reason for this celestial phenomenon is that it came 41 hours after the Moon reached apogee, its farthest point from Earth. The farther away the moon is, the longer it takes to travel along, resulting in more time to move out of Earth's shadow.

The November 19 partial lunar eclipse sustained its record for another four thousand years as the six-hour-long partial lunar eclipse will likely happen on October 9, 2489. There are 973 partial lunar eclipses between the years 1451 to 2650.

The last we saw such a long lunar eclipse was on November 9, 2003, which spanned for six hours and three minutes. However, it was not a partial total lunar eclipse.

At least two partial lunar eclipses happen every year, but total lunar eclipses are rare. Unlike solar eclipses, it is safe to look at a lunar eclipse. Parental guidance is very important though.

Where can you watch the Partial Lunar Eclipse In India?

People in northeast India were able to view the final phases of the partial lunar eclipse. The eclipse was visible in parts of Arunachal Pradesh, Assam, and neighboring regions. Some even took beautiful pictures of the eclipse. We must consider ourselves lucky to witness this phenomenon.
