A faint optical flash in dust-obscured GRB 080603A: implications for GRB prompt emission mechanisms

We report the detection of a faint optical flash by the 2-m Faulkes Telescope North simultaneously with the second of two prompt γ-ray pulses in INTEGRAL gamma-ray burst (GRB) 080603A, beginning at t rest= 37 s after the onset of the GRB. This optical flash appears to be distinct from the subsequent...
