The Troublesome Broadband Evolution of GRB 061126: Does a Gray Burst Imply Gray Dust?
We report on observations of a gamma-ray burst (GRB 061126) with an extremely bright (R ≈ 12 mag at peak) early-time optical afterglow. The optical afterglow is already fading as a power law 22 s after the trigger, with no detectable prompt contribution in our first exposure, which was coincident …
