The "blood moon" label is what's getting the online attention today, but even serious astronomers are getting excited about a series of four total lunar eclipses starting on April 14.

Actually, for most of the United States, the first eclipse will fall on April 15, but on the West Coast it will begin around 10 p.m. April 14, with the total phase from just after midnight to about 1:20 a.m.

In the shadow of the earth, the moon will appear dusky red.

The three other eclipses in the "tetrad" will be in October, April 2015 and September 2015. All will be visible in at least part of the United States.

Another sky event this month will have a smaller audience: Prime viewing for an annular or "ring of fire" solar eclipse on April 29 is limited to a little part of Antarctica, although partial views will be seen in other areas of the Southern Hemisphere.
