The robotic 60-cm REM telescope located at La Silla (Chile) observed 
automatically the field of the GRB 080727B (Immler et al. GCN 8022) on 
July 27 starting at 08:14:25 UT (61 seconds after the burst). 
Observations were carried out at high airmass. In a series of 10s and 
30s exposures we do not see any afterglow candidate inside the XRT error 
box down to R > 16.0 and H > 13.0 (3sigma c.l.).
