Moffat, A. F. J. ; Marchenko, S. V. Abstract Two years of nearly-daily UBV monitoring of the variable WR star HD 191765 have yielded evidence for a relatively long, 37.2-day period of the light curve in all three filters. In view of the additional 2-day periodicity that emerges from the data, this long period may be interpreted as either (1) luminous, blue-variablelike microvariability, or (2) the precession of the WR component in a close binary system with P of about 2d.
