43203 2000 AV70 is a main-belt asteroid with an estimated diameter of 5 km. It was discovered on January 5, 2000, by LINEAR at Socorro. The semi-major axis is 2.38 AU, the eccentricity is 0.228 and the inclination is 4.96 degrees.
This asteroid was observed on 5 nights between June 17 and June 21, 2007. Assuming a normal double peaked lightcurve, the best period found was 14.83 hours, however coverage of this period was not complete. A plot of half this period is included, and shows a good agreement, so I would expect that the 14.83 hour period is close to the actual. More observations at future oppositions would be useful.
