INFORMATION BULLETIN ON VARIABLE STARS Number 2835 Konkoly Observatory Budapest 17 December 1985 HU ISSN 0374 - 0676 PHOTOELECTRIC OBSERVATIONS OF R CrB The star R CrB was observed photoelectrically with the 165 mm Newtonian reflector at Nessa Observatory using standard UBV filters. Delta CrB (V= 4.63m, B-V = 0.80m, U-B = 0.37m) and SAO 084005(V = 7.45m, B-V = 0.44m, U-B = 0.02m) were used as comparison stars. These observations are the continuation of those published in IBVS No.2646. Table I.
