Baldovin-Saavedra (ISDC & Geneva Observatory) report on behalf of a
larger collaboration:
We observed the field of GRB091127 (Troja et al., GCN 10191) with the
Nordic Optical Telescope equipped with StanCam and NOTCam, starting at
00:36:03 UT on Nov. 28th, 70.3 mins after the burst.
Preliminary data analysis confirms the bright optical afterglow (Smith
et al., GCN 10192; Immler et al., GCN 10193) and shows
R~16.3 at 00:38 UT
I~16.2 at 01:09 UT
R~16.5 at 01:15 UT
J~15.9 at 01:43 UT
H~15.4 at 01:34 UT
K~14.8 at 01:26 UT.
The R-band afterglow light curve is decaying slowly during our
observations.
