The Near-Graze of Nu Virginis

And Lunar Motion

Nu Vir graze Nu Vir graze
The Moon (its nighttime side illuminated with Earthlight) just barely misses a grazing occultation of Nu Virginis on July 14, 2002, the star seen just to the left of the upper horn of the bright crescent. The pictures, taken 5 minutes apart, clearly show the easterly lunar motion. The irregular outline of the bright crescent (the sunrise line on the Moon) is caused by high areas catching the first rays of sunlight contrasted with low basins still in shadow.
