Super blue blood moon makes first appearance since 1866
On Wednesday, January 31, a super moon, blue moon and a lunar eclipse have coincided for the first time since 1982 and will not occur again until 2037.
The second full moon in a calendar month is a blue moon. This one also happens to be an especially close and bright moon, or supermoon. Add a total eclipse, known as a blood moon for its red tint, and it's a lunar showstopper, ABC News reports.
NASA is calling it a lunar trifecta: the first super blue blood moon since 1982. That combination won't happen again until 2037.
A lunar eclipse occurs when the sun, Earth and moon line up perfectly, casting Earth's shadow on the moon.
The super blue blood moon has been observed in Russia, Ukraine, Belarus, Moldova, Baltic States, as well as North America, Alaska and Hawaii. South America and Africa were out of luck for the eclipse.
The residents of Yerevan, Armenia’s capital, have also caught the glimpse of the unique lunar phenomena.
