| Abstract: |
We present the preliminary results of a BVRI photometric monitoring of the circumpolar BL LAc object S5 1803+78 started in April 1996. The source luminosity showed an overall variation of about 2.4 mag in all the bands. The brightest level (R=3D13.8) was observed in September 1997 and after that the flux declined for 20 days at a mean rate of 0.07 mag/day. |
