GRO J0422+32
     P. Zhao, P. Callanan, M. Garcia, and J. McClintock, Smithsoni-
an Astrophysical Observatory, report: "The x-ray nova GRO J0422+32,
which is currently in outburst (IAUC 5901), continues to brighten
optically.  CCD photometry obtained with the F. L. Whipple Observa-
tory's 1.2-m telescope gives the following magnitudes (+/- 0.02):
Dec. 10.35 UT, R = 14.89; 10.47, 14.81; 13.12, R = 14.92, V =
15.21; 14.09, 14.90, 15.16; 14.37, 14.87, 15.13.  The nova has
brightened by > 0.5 mag during the past 6 days; it is now brighter
than the reported maximum of the outburst that occurred this past
August (IAUC 5842, 5844)."
