Photoelectric observations and light curves analysis of V502 Ophiuchi The B and V photoelectric observations of the eclipsing system V502Ophiuchi obtained during 1986 at the Kryonerion Astronomical Station ofthe National Observatory of Greece are given. New photoelectric andabsolute elements of the system are given and a new ephemeris formula isproposed which fits better the present observations, since the period ofthe system continues to decrease.
