Supermoon is a term used to describe when the moon is full and closest to the Earth, appearing 15% brighter and 30% larger than a regular full moon. The moon experiences perigree once per orbit, but that doesn't always coincide with a full moon. "The red/blood moon is possible because while the moon is in total shadow, some light from the Sun passes through Earth's atmosphere and is bent toward the moon", SCS said.
For the first time since March 31, 1866, we'll have a total lunar eclipse that happens during the second full moon of a calendar month and also happens to occur when the full moon is near the point of its orbit that brings it closer to Earth.
The last time all that happened together was nearly 152 years ago.
To make the event even more spectacular, the full moon will also be a supermoon like the one on January 1. The New Year marked the day for two of the three supermoons one after the other which has been dubbed by NASA as the "Supermoon trilogy".
NASA offers advice on when to look out for this super blue blood moon.
The first full moon for this year happened last January 2, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.

As long as there is not too much cloud, the moon should be clearly viewable in the sky.
The month's second full moon on January 31 is known as a blue moon. The second one is marked by a blue moon.
NASA has announced that the supermoon at the end of the month will feature a total lunar eclipse.
For the Indian subcontinent, the Middle East and Eastern Europe, the Blue Moon total eclipse will already be underway as the Moon rises. The duration of the total phase is 77 minutes, with the moon tracking through the southern part of the Earth's shadow.
Here is everything you need to know.
Along the U.S. West Coast, the total phase begins at 4:51 a.m. PST.
