It sounds menacing, but a super blue blood moon actually gets its catchy name from a perfect storm of lunar occurrences. The next one is coming January 31. There will be no werewolves, but there will be a spectacular celestial sight on tap for moon watchers.

Let's pull that name apart. A super moon happens when a full moon is at its closest point in orbit to Earth (also known as perigee). A blue moon is the name given to a second full moon within a calendar month. We already logged a super moon on January 1. A blood moon happens during a total lunar eclipse when the moon takes on a reddish hue.

The lunar eclipse will be visible in parts of North America, Australia, the Middle East, Asia and Russia. You can consult NASA's total lunar eclipse map to find out if and when it will be viewable at your location. The total lunar eclipse will be fully visible in Dhaka. "Weather permitting, the West Coast, Alaska and Hawaii will have a spectacular view of totality from start to finish," says NASA lunar blogger Gordon Johnston. Moon viewers in those areas will need to get up very early in the morning.

If you don't live in one of those zones, or if weather gets in the way, you can still enjoy the experience by tuning in to NASA TV's live feed. The Griffith Observatory in Los Angeles will also present a live online look at the eclipse.

Johnston's delightful moon blog covers all the other names associated with this particular January 31 moon: the long night moon, the wolf moon, the snow moon, the ice moon, the old moon or the moon after Yule. Whatever you want to call it, it should be beautiful to behold.
