Data Points: 223
Discovered: 1932-04-24  Heidelberg  K. Reinmuth
Family/Group: NEA
Taxonomic Class: Q
Published: MPB 33, 39-41
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

The amplitude of the asteriod changed dramatically over the 2 weeks it was observed. The data have been overlayed to that the maximums at 0.8 phase were equal.
