Family/Group: MB-Outer
Taxonomic Class: C
Published: MPB 31, 29-33
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 paper gives a period of 6.551 h. After re-measuring the original images to provide more accurate night-to-night calibration, there appeared to have been a long-term component of 40-60 h with A ~ 0.3 mag. It's possible that previous works, all using relative photometry, forced zero point shifts that hid the long-term characteristics of the curve.
