1947 XC. Discovered 1947 Dec. 12 by H. L. Giclas at Flagstaff.

Named for the place of Moonlight Water near Monument Valley, Utah, on the Navajo Indian Reservation. During the day the hot Sun evaporates the small amount of spring water that seeps up through the sand. During the night, with less evaporation, the sand becomes moist enough to reflect the light of the Moon. (M 7782; M 8025)

This Apollo object was rediscovered as 1979 XA on 1979 Dec. 13 by Q. Passey and S. J. Bus at Palomar.
