Apr. 15, 3:42 a.m. EDT: Full Pink Moon —The grass pink or wild ground phlox is one of the earliest widespread flowers of the spring. Other names were the Full Sprouting Grass Moon, the Egg Moon, and —among coastal tribes —the Full Fish Moon, when the shad come upstream to spawn. In 2014 this is also the Paschal Full Moon; the first full moon of the spring season.
The first Sunday following the Paschal Moon is Easter Sunday, which indeed will be observed five days later on Sunday, April 20. This full moon will also undergo a total lunar eclipse and North America will have a ringside seat for it, as it will occur between midnight and dawn depending on your location. Totality will last almost 78 minutes. [Amazing Photos of a Total Lunar Eclipse]
The series of 4 total lunar ecplises is called a Tetrad. [Total Lunar Eclipse of April 15 Explained (Video)]
