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".] [GCN OPS NOTE(09may09): Per self request, D.Malesani was removed from the author list.]
