Description
During the international OJ-94 campaign we have also monitored blazar 3C
66A. Since fall 1993 we have collected over 500 V-band observations.
This constitutes more data than all the previous observations put
together. During this monitoring the blazar was in outburst reaching
V-magnitude 13.7 (JD 9414). This is the brightest it has ever been
observed. The light curve shows continuous activity in time scales from
tens of minutes to days and weeks. The largest observed variations are
of the order of one magnitude in a few days. Overall the light curve
shows small amplitude flickering (0.2 mag) in timescales from hour to
days and six separate outbursts of 0.5 mag, each lasting about one week.
This fall the light curve has shown strong brightening from early
September, until mid October , with the small amplitude flickering. Here
we present the observed V-band light curve with preliminary analysis.
