Vitali report on behalf of the REM team:
The robotic 60-cm REM telescope located at La Silla (Chile) observed
automatically the field of the GRB 081222 (Grupe et al. GCN8691)
starting about 28s after the burst. We detect a bright object in
our first H-band image inside the XRT error box at the following
coordinates (J2000):
R.A. = 01:30:57.59
Dec = -34:05:41.7
with an uncertainty of about 1.0". The object is approximately H~11.1
at about 1min after the burst and faded rapidly during the next
observations.
Further observations are in progress
