	    PHOTOELECTRIC OBSERVATIONS OF R CrB

  The rise from a recent deep minimum of RCrB was observed photoelectrically
with the 165mm Newtonian reflector at Nessa Observatory using standard UBV
filters. Delta CrB (V=4.63, B-V = +0.80, U-B = + 0.37) and SAO 084005 (V=7.45,
B-V=+0.44, U-B=+0.02) were used as comparison stars. These observations are
the continuation of those published in IBVS 2442.
