Astrometric measurements are by me. The imagery was obtained in twilight at the end of a run of the Szeged Asteroid Survey. Each image was a 3 second exposure only! The magnitude data nicely detail a part of the periodic brightness variation. The Chang'e 3 rb was at a distance of about 195 000 km (0.5 Lunar Distance) during these observations, moving towards perigee.
