Continuous optical monitoring during the prompt emission of GRB 060111B
Continuous optical monitoring during the prompt emission of GRB 060111B
Aims.We present the time-resolved optical emission of GRB 060111B during its prompt phase, measured with the TAROT robotic observatory. This is the first time that the optical emission from a gamma-ray burst has been continuously monitored with a temporal resolution of a few seconds during the prompt gamma-ray phase.
