| 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. |
