The radio and optical behaviour of the BL Lacertae object 0716+714 from 1994 to 2001 has been investigated by a wide international collaboration including eight optical telescopes in Italy, Greece, Georgia (FSU), and Uzbekistan and two radio antennas in USA and in Finland. The optical light curves show a long-term trend on which fast variations are superposed. The mean brightness level seems to vary with a typical time scale of about 3.3 years. No clear evidence of correlation between variations in the optical and radio bands has been found.

Abstract
The radio and optical behaviour of the BL Lacertae object 0716+714 from 1994 to 2001 has been investigated by a wide international collaboration including eight optical telescopes in Italy, Greece, Georgia (FSU), and Uzbekistan and two radio antennas in USA and in Finland. The optical light curves show a long-term trend on which fast variations are superposed. The mean brightness level seems to vary with a typical time scale of about 3.3 years. No clear evidence of correlation between variations in the optical and radio bands has been found.File in questo prodotto:
