OPTICAL PHOTOMETRY OF THE EMISSION-LINE M-STAR PC-0025+0447

We present r, i, and z CCD photometry of the emission-line M star PC 0 025+0447 obtained in 1992 December. The optical colors of this object are significantly redder than the colors of late M-type stars. Combini ng these data with the earliest images we have of the object provides a time baseline of just over six years. The data are consistent with n o detectable proper motion; an upper limit on the proper motion is 0'' .04 yr-1. We also report a position for PC 0025+0447 that should be ac curate to almost-equal-to 1''.
