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 on Sep 16 starting from about 20 s after the GRB time. We see a source not present in the 2MASS catalogue with approximately H~14.5 one minute after the burst at the coordinates RA=22:25:06.19, DEC=-57:01:24.1 (error 1 arcsec). Further observations are in progress. [GCN OPS NOTE(16sep08): The author requests that people should use the 8238 Circular as the primary source. The 8239 Circular was the result of multiple efforts of a distributed team.] [GCN OPS NOTE(16sep08): Per author's request, DM was removed from the author list.]
