Data Points: 140

Family/Group: Eos
Taxonomic Class: S (Assumed)
Published: MPB 38, 52-54
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 29, 14-15: P = 6.53, A = 0.25. Remeasuring the images using the 2MASS conversions found the revised period, which was closer to agreeing with the results obtained from the 2005 apparition (33, 58-62).
