              NOTE ON THE CLASSIFICATION
                      OF BC ERI

     The General Catalog of Variable Stars lists BC Eri as an RRc
of period 0.264 day, and it was placed on the University of Arizona
program of multi-color observations of RR Lyrae stars.
     When the B-V index was found to be nearly constant (+0.34
mag.) from minimum to maximum light, the star's classification 
became suspect and further observations were secured. These show the
minima, of alternately unequal depths, to have a narrow, symmetrical
shape while the maxima are broad and smoothly rounded, so that there
can be no doubt that BC Eri is actually a W UMa type star of period
0.528 day.
     We do not yet have a complete light curve, but we can state
that Vpri=11. 32, Vsec=11.26, and Vmax=10.83 mag.  approximately.
