Family/Group: Hungaria
Taxonomic Class: ES (Assumed)
Published: MPB Pending
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

Followup to 2010 observations. 2012 results contradict earlier results of 5.15 h, when amplitude was 0.13 mag. A solution of 3.943 can be found using 2010 data, but it's not quite as good as the 5.15 solution.
