Data Points: 318
Discovered: 1925-04-22  Heidelberg  K. Reinmuth
Family/Group: MB-Outer
Taxonomic Class: C
Published: MPB 37, 127-130
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

Originally reported in MPB 32, 90-92 with P = 16.26, A = 0.10, U = 2. Remeasuring using 2MASS to BVRI conversion (Warner, MPB 34, 113-119) to calibrate sessions found a long period object. This points out the need to calibrate all data on at least an internal system to 0.05 mag or better (preferably much better for critical work).
