Abstract

We present some results based on early-time gamma-ray burst follow-up data obtained with the RoboNet 1.0 network, which consists of three 2 m fully robotic telescopes, combined with the X-ray data taken with the Swift X-Ray Telescope. Here we focus on two bursts recently discovered by Swift: GRB 060206 and GRB 060108. In particular, the combination of sensitivity and rapidity of our optical facilities allowed us to detect fast colour changes undergone by the afterglow of GRB 060206, and made it possible to detect the counterpart to GRB 060108, which turned out to be one of the faintest optical afterglows yet discovered at early epochs. We discuss the interpretations given in either case and some implications on the circumburst environment of these bursts.
