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
