Mysuru: December 26, 2019 seems to be really memorable and astounding for Indians, as everyone witnessed the spectacular annular solar eclipse! Eventhough it was overcast and murky from Mysuru and Bengaluru, somehow Mysoreans managed to see to this rare astronomical spectacle with utmost difficulty.

Suddenly all may start to think, why speaking about eclipse now? The answer is very obvious.

On November 30, a few parts of the globe can witness the years’ last lunar eclipse. The most conspicuous, amazing, striking, impressive and evident astronomical event in the sky is an ‘Eclipse’.

None can forget the mesmerizing Supermoon, Bloodmoon total Lunar Eclipse that occurred on January 31 and July 27 of 2018! This astronomical occurrence has been memorable and millions witnessed this spectacular spectacle. Last year on July 27 – 28, Indians were greatly privileged to witness a regular longest duration ‘Total Lunar Eclipse’ of this century.

This year, we were extremely privileged to witness three Penumbral Lunar Eclipses and one partial solar eclipse from any part of India. All penumbral lunar eclipses in 2020 are hard-to-see, whereby the moon misses the dark umbra but travels through the outer faint penumbra.

However, penumbral eclipse on June 5 – 6, 2020, was quite awesome to notice a strawberry moon.

But the eclipse will not visible from Mysore at the eclipse on November 30 as its starts from 1:04 pm and ends by 5:22 pm. We had a chance of detecting the slight darkening on the full moon’s face will come at or near maximum eclipse.

This form of eclipse was visible from all parts of India. This eclipse was visible in the region covering Europe, Asia, Australia, and Africa. Most penumbral lunar eclipses cannot be easily distinguished from a usual Full Moon.

Lunar eclipses, which may be total or partial, can occur only at full moon when Sun, Earth and Moon are in line. As the Sun is an extended light source, Earth’s shadow has two components – a dark, central UMBRA, where the Sun is completely obscured, and a lighter outer PENUMBRA, within which the obscuration is partial. During a lunar eclipse, the Moon passes first through the penumbra, taking about an hour, moving eastward by its own diameter in this time, to reach the western edge of the umbra.

A Lunar eclipse occurs when the Moon passes through the umbral region of the Earth’s shadow and becomes imperceptible. Lunar eclipse is discernible from a large part of the Earth. Penumbral lunar eclipse on November 30 shall be visible from Northern and southern parts of America, Australia, Europe, Pacific and a few parts of Asia.
