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 091109 (Oates et al. GCN10138) starting about
77 s after the burst. We detect a faint object in the XRT error circle in our
first H-band images at H~14.8 at coordinates: RA(J2000) 20:37:02.2; Dec(J2000)
-44:09:30.4 with 1 arcsec error.
