Title of the communication: Spectral variability in 3C66A observed during a multifrequency monitoring campaign.
Preliminary abstract (12 lines max.):
BL Lac object 3C66A has been monitord for three years during the
OJ-94 project. It has been seen about one magnitude brighter than
its historical light curve indicates. The light curves show
continuous variability from time scales of tens of minutes to
weeks. Here we will present results from this monitoring,
concentrating on the spectral variability and its correlations with
objects brightness.
