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 080916 (Ziaeepour et al. GCN 8237)  
on Sep 16 starting observations about 19.4 sec after the GRB. We  
clearly detect a NIR source at RA(J2000)=22:25:06.13, Dec.(J2000) 
=-57:01:22 with an uncertainty of 1" which is compatible with the  
position of the UVOT source (Ziaeepour et al. GCN 8237). At the  
beginning of the observation the source had a magnitude H=14.0+/-0.3,  
calibrated against 2MASS. The source showed a clear fading behavior  
during the REM observation.
