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 090509 (Grupe et al. GCN9325)
starting about 3min after the burst. We detect a fading object in
the BAT error circle in our first H-band images at H~14.3 at
coordinates: RA(J2000) 16:05:38.99; Dec(J2000) -28:23:58.7 with 1
arcsec error. Moon is only at about 15 deg preventing useful optical
observations.
[GCN OPS NOTE(09may09): Per author's request, the "R~14.3" was changed
to "H~14.3".]
