Description:
    We report the BVRcIc  data for  10 blazars  observed in  the first
    phase of a  long-term  photometric  monitoring  program  of  about  30
    objects. The  observations were  carried out  with a  0.40-m automatic
    imaging telescope, recently developed by  our  group  at  the  Perugia
    University  Observatory. During our period of observation 1215+303 and
    1424+240 were at their highest values of magnitude, while 0754+100 and
    0829+043  displayed large amplitude flares.  We further report optical
    data  of Mrk 501 during the same period in which TeV γ-rays were
    detected by  the Whipple Observatory.  
    For a description  of the (RI)c photometric system, see e.g. the 
    General Catalog of Photometry Data GCPD/54.
