North of Grimaldi crater, lunar surface

During the Apollo 17 mission in December 1972, Command Module Pilot Ronald Evans reported "very bright particles or fragments or something" drifting past the spacecraft during a maneuver at Day 00, 03:34:10. Lunar Module Pilot Harrison Schmitt described the view as looking "like the Fourth of July," while Mission Commander Eugene Cernan estimated the fragments as "flat, flakelike particles," some possibly 6 inches across and twinkling. Evans speculated the fragments might be ice chunks or paint from the S-IVB stage but called that "a wild guess."
