Baldovin-Saavedra (ISDC & Geneva \nObservatory) report on behalf of a\nlarger collaboration:\n\nWe continued to observe the field of GRB091127 (Troja et al., GCN 10191; \nSmith et al., GCN 10192; Immler et al., GCN 10193) at the Nordic Optical \nTelescope equipped with StanCam. Among a series of observations, a 60 s \nR-band frame was obtained staring at 21:51:50 UT on Nov. 28th, 22.4347 \nhr after the burst trigger.\n\nThe optical afterglow is clearly detected in the frame. The magnitude is \nR=18.95+/-0.04, calibrated with the reference star #0710-0025176 \n(R2=14.02) in the USNO B1 catalog. Comparison with our previous \nobservation (Xu et al., GCN 10196) indicates a decay slope of ~0.8 \nbetween the two epochs.",
