NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

MPB 37, 127-130: P = 9.37, A = 0.30, U = 2-, based on data from two nights in 2001 that did not cover the entire curve. This data set does not give an acceptable fit when using the period of 9.361 found by Szekely (Plan. Space Sci. 53, 925-936.
