Washington saw a particularly beautiful full vernal moon, better known as the Full Worm Moon, on Thursday, and a number of our Flickr contributors added their best shots of it to the DCist Pool. Here’s what the Farmers’ Almanac has to say about the Full Worm Moon:

As the temperature begins to warm and the ground begins to thaw, earthworm casts appear, heralding the return of the robins. The more northern tribes knew this Moon as the Full Crow Moon, when the cawing of crows signaled the end of winter; or the Full Crust Moon, because the snow cover becomes crusted from thawing by day and freezing at night. The Full Sap Moon, marking the time of tapping maple trees, is another variation. To the settlers, it was also known as the Lenten Moon, and was considered to be the last full Moon of winter.

Neat. And all well and good, except the temperature outside still feels rather wintery to us, even during the day. Take comfort, though. Jason Samenow says that “Friday should be mostly sunny and delightful with highs temperatures in the mid 60s.” Hurrah!
