The RC-band light curve of GRB 060526 fitted with a double smoothly-broken power law, using data starting at 0.046 days. The residuals of the fit show an early optical flare and later strong variations of up to 0.3 mag. The dashed vertical lines mark the break times, the dotted lines the 1σ region of uncertainty. The second break is soft (n ≈ 4) and is thus seen as a smooth rollover.
