“X” (and “V”) marks the spot!

Two of my favorites (okay, I have many) - but these are a treat to spot - Lunar X and Lunar V.

Per Wikipedia: “The Lunar X (also known as the Werner X) is a clair-obscur effect in which light and shadow creates the appearance of a letter ‘X’ on the rim of the Blanchinus, La Caille and Purbach craters.”

“The X is visible only for a few hours before the first quarter, slightly below the lunar terminator. Near to the X, the Lunar V is also visible, formed by Ukert crater and several other small craters.”
