Title of the communication: Monitoring of Blazars at Tuorla Observatory.
Preliminary abstract (12 lines max.):
We present preliminary result from monitoring a sample
of blazars at Tuorla Observatory. We have a Peltier cooled CCD, with
V-filter on the one meter telescope. Since last fall we have observed
during 85 nights. A total of 3000 observations on 20 objects have
been collected. A lot of these observations have been made in connection
with international multifrequency campaigns that have included
satellite observations by EGRET, ROSAT, IUE and XTE.
We will describe our telescope and detector systems
and show some preliminary results.
