Werner X sightings for 2014

Posted by as Special Events, Uncategorized

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. To find the X look along the lunar terminator, the line between dark and light, start at about the middle and follow it slightly south. Near to the X, the Lunar V is also visible, formed by Ukert crater and several other small craters.
