Simultaneous optical multiband observations of the Blazar S5 0716 +714 were performed using the 70 cm telescope of the University of Roma (Italy), the 70 cm of the Collurania-Teramo Observatory, the 50 cm of the Vallinfreda Station (Roma, Italy) and the 40 cm of the University of Perugia (Italy). Standard B,V,R,I and narrow band at 720, 800, 860 and 990 nm filters of the Arizona system were used. Using several telescopes it is possible to achieve a very tight temporal sampling in a number of spectral bands and to look for possible different behaviours of the light curves at different wave-lengths. Even intranight trends as small as a few hundredth of magnitude can be unambiguously detected. The results of several days of observations are shown and discussed in the framework of current models.

Abstract
Simultaneous optical multiband observations of the Blazar S5 0716 +714 were performed using the 70 cm telescope of the University of Roma (Italy), the 70 cm of the Collurania-Teramo Observatory, the 50 cm of the Vallinfreda Station (Roma, Italy) and the 40 cm of the University of Perugia (Italy). Standard B,V,R,I and narrow band at 720, 800, 860 and 990 nm filters of the Arizona system were used. Using several telescopes it is possible to achieve a very tight temporal sampling in a number of spectral bands and to look for possible different behaviours of the light curves at different wave-lengths. Even intranight trends as small as a few hundredth of magnitude can be unambiguously detected. The results of several days of observations are shown and discussed in the framework of current models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
