Lightcurve results for 24391 2000 AU178.
Period 5.436 +/- 0.002 hours. Amplitude 0.6 +/- 0.1 magnitude.
24391 2000 AU178 is a main belt asteroid with an estimated diameter of 20 km. It was discovered on January 7 2000, by the Lincoln Laboratory Near-Earth Asteroid Research Team at Socorro. The semi-major axis is 2.34 AU, the eccentricity is 0.185 and the inclination is 13.56 degrees.
This asteroid was observed on four nights between August 6 and 18, 2006. Despite repeated attempts, no simple solution to the lightcurve could be found. The best result was the lightcurve included here. This curve 3 or possibly 4 peaks of varying heights, and a period of 5.436 hours. Certainly much more work is required for this asteroid.
