Description:
We report the BVR_c_I_c_ 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 {gamma}-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>.
