Abstract:
The optical (BVRI) and infrared monitoring data covering 2 years for 10
radio-selected BL Lac objects and the simutaneous observations of optical
and infrared for BL Lac and 3C 66A are presented here. Seven sources exhibit
short time-scale variability, and two sources exhibit medium time-scale
variability.
