Abstract
ABSTRACT We present r, i, and z CCD photometry of the emission-line M star PC 0025+0447 obtained in December 1992. The optical colors of this object are significantly redder than the colors of late M-type stars. Combining this data with the earliest images we have of the object provides a time baseline of just over six years. The data are consistent with no 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 accurate to ~1".
