Abstract

We report the detection of early (60-230 s) optical emission of the gamma-ray burst afterglow of GRB 071010B. No significant correlation with the prompt γ-ray emission was found. Our high time resolution data combining with other measurements within 2 days after the burst indicate that GRB 071010B is composed of a weak early brightening (α ∼ 0.6), probably caused by the peak frequency passing through the optical wavelengths, followed by a decay (α∼0.51), attributed to continuous energy injection by patchy jets.
