There was a total eclipse of the moon on the night of September 27-28, 2015. It happens to be the closest supermoon of 2015. It’s the Northern Hemisphere’s Harvest Moon, or full moon nearest the September equinox. It’s the Southern Hemisphere’s first full moon of spring. This September full moon is also called a Blood Moon, because it presents the fourth and final eclipse of a lunar tetrad: four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. Phew!
