AbstractMultiwavelength observations of gamma-ray burst afterglows are presented, in particular those in the optical and millimetre wavelengths. I will focus on the observations mostly carried out at Spanish ground-based observatories (mainly the 10.4m GTC) and at the Plateau de Bure Interferometer in the French Alps. The importance of global networks of robotic telescopes (like BOOTES, established worldwide) for early time observations in order to put constraints on the physical mechanisms of the GRB early time emission phase is also discussed. The overall observational efforts provide additional clues for a better understanding of the reverse and forward shock. Finally I will report on the Lomonosov/UFFO-p capabilities taking into account its launch in 2012.

Polarization Detection

Polarization offers the capacity to diagnose the structure of the magnetic fields in the GRB ejecta which could provide a clue to pin down the jet acceleration process. The recent early-time polarization detection at about 10% level opens the exciting possibility of measuring the time-resolved evolution of polarization degree and angle of early optical afterglow.
