	Family/Group:	MB-middle
	Taxonomic Class:	SC (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) Full moon project. Initial result of 6.09 h contradicted earlier result (Ditteon, R.; West, J. (2011) Minor Planet Bul. 38, 214-217, U = 3). Additional data at PDO in 2012 found the "correct" period.
