摘要：Born in 1997, the Whole Earth Blazar Telescope (WEBT) is a network of optical, near-infrared, and radio telescopes that in concert have the capability to obtain continuous, high-temporaldensity monitoring of blazars during time-limited campaigns on specific objects. The GLAST-AGILE Support Program (GASP) was organized within the WEBT to provide optical-to-radio long-term continuous monitoring of a list of selected g -ray-loud blazars during the operation of the AGILE and GLAST satellites. We present the results of the first GASP effort, targetting the BL Lac object 0716+714 in September–November 2007, when the source was detected by AGILE. In October an outburst was detected simultaneously in the optical and radio bands. We also show some results of the last WEBT campaign on the quasar-type blazar 3C 454.3 in the 2007–2008 observing season. In this period 3C 454.3 was very active, showing pronounced optical outbursts, and it was detected by AGILE in July and then in November–December. Moreover, several noticeable episodes of very fast (i.e. intranight) variability were observed in the optical light curves.
