The binary system SS433 is a well known object for its unique moving emission line features and its relativistic jets. Observation of SS433 in many wavelength bands show two basic periods, a 13-day orbital period and a 160-day precessional period of the jets. In order to research these two periods and the extreme brightness drop which occur very rarely in the primary minimum phase of 13-day orbital period, we obtained CCD frames of SS433 in the V photometric band during 1987-1993 with the 60 cm reflector at KSC (Kagoshima Space Center). Analysis results confirmed that these two periods have not changed in the past 6 years, and the extreme brightness drop did not appear in our observations.
