Observations on 2013-070B, the Chang'e 3 rb, at a distance of about 388 000 km
(~1.0 Lunar Distance), using the 0.51-m telescope of MPC Q65 Warrumbungle in
Australia.

The brightness determinations from the series above, obtained with the help of
telescope operator Peter Starr who took some extra images for me, provides a
nice pattern of assymetric saw-tooths with a period of ~7 minutes.
