If you’re in North America and the Pacific, you may be able to see a very subtle partial penumbral eclipse of the Moon on the morning of March 23, 2016. Western North America has the eclipse taking place in its sky from start to finish. Look for the eclipse shortly before dawn breaks.
The Moon will look full tonight but it still is a waxing gibbous moon until it “officially” is full on March 23 at 12:01 Universal Time (8:01 a.m. EDT).
There are many names for the monthly Full Moons. I try to choose a new one each year and this time I selected the Earth Cracks Moon. That sounds rather ominous, but it only refers to the heaving soil as we transition into spring with cold nights and warm days. Another name – the Full Worm Moon – also refers to the thawing ground and the earthworm casts that can appear, which delights the robins.
Those names and the Full Crust Moon are all more common with Indian tribes than with the European settlers, though in northern climes all parties would have observed both natural occurrences. To the settlers, it was known by names such as the Lenten Moon and Full Sap Moon, marking the time of tapping maple trees.
Some northern tribes knew this as the Full Crow Moon, because the cawing of crows signaled the end of winter, but look at all the names I have uncovered for this winter-into-spring Full Moon: Fish Moon, Medieval Chaste Moon, (Choctaw) Big Famine Moon, (Cherokee) Windy Moon, (Dakotah Sioux) Moon When Eyes Are Sore from Bright Snow, (Celtic) Moon of the Winds, Oak Moon, Storm Moon, Seed Moon, Maple Moon, Chaste Moon, Strong Wind Moon, Moon of Wakening, Light Snow Moon, Flower Time Moon, Cactus Blossom Moon, Rust Moon, Spring Moon, Whispering Wind Moon, Windy Moon, Death Moon, Sleepy Moon, and Big Famine Moon.
