Partial phase of the April 14-15, 2014 total lunar eclipse – photo by Fred Espenak

As I wrote last weekend, there is a total eclipse of the moon tonight (September 27-28, 2015).  Being that it is also the closest of this year’s supermoons, there is more drama to the event. For those of us north of the equator, it is a Harvest Full Moon (the one nearest the autumn equinox). It is many named lunar events!

You might also hear the term “Blood Moon” used because this is the fourth and final eclipse in four straight total eclipses of the moon, spaced at six lunar months (full moons) apart. That is known as a lunar tetrad.

The total lunar eclipse is visible from the most of North America and all of South America after sunset tonight.
