The total lunar eclipse, which can be seen from everywhere in India, with the moon taking a red brown glow, also called the "Blood Moon" began at 5.20 pm on Wednesday with what is called the partial shadow or penumbra of the earth's shadow striking the moon.
The event would also bring about the Blue Moon and the Super Moon phenomena, a release from the BM Birla Science Centre said.
Meanwhile, sky gazers and photo enthusiasts are making a beeline for the Aryabhatta Research Institute of Observational Sciences perched at an altitude of 2,450 metres in Nainital to witness the lunar delight on January 31- a blue moon, blood moon and a super moon.
The main eclipse will start around 6.25 pm after sunset and this can be seen in the eastern sky as the moon would have just risen by then.
During the lunar eclipse, the earth comes exactly between the sun and the moon and the earth's shadow falls on the moon.
"If the three are almost exactly on the same line, we have a total lunar eclipse. Even during a total lunar eclipse, some of the sun's rays get refracted through the earth's atmosphere and strike the moon, which thereby takes on a low brown red glow which is what will happen on January 31st. Some people call this the Blood Moon," BG Sidharth, Director, BM Birla Science Centre, said.
The release informed that this would be the second full moon in the month and it is often called the "Blue Moon".
It said that the positions and distances of the moon and the earth, relative to the sun on this occasion, were such that the moon would appear slightly bigger (about 10 per cent or more) and a little brighter on this day.
"Such a circumstance is called a Super Moon. What this means is that there may be slightly higher tides in rivers and seas that day but nothing very alarming," the release said.
The release informed that superstitious beliefs, like not eating anything during a total lunar eclipse, have no scientific basis whatsoever.
