Title of the communication: Ten years of infrared and optical monitoring
of blazars in the Canary Islands.
Preliminary abstract:
Near infrared (JHK) monitoring of a sample of blazars started
with the 1.5m telescope in Teide Observatory (Tenerife) in 1988
and has continued ever since, whilst visible monitoring with
various telescopes in El Roque de los Muchachos Observatory and,
later, Teide Observatory, has been carried out since
1986. The observations show a range of phenomena, including
major outbursts and microvariability. Sample light curves of various
blazars including OJ287, 3c345, 3c279 and 3c66 will be
presented. Some of these objects show major changes in their
spectral energy distribution at different levels of activity.
