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 080409 (Holland et al., GCN 7573) starting about 81 seconds after the burst. Airmass was large (about 2.9). Preliminary photometry of our earliest images (R: 30 s, H: 50 s) reveal no new sources inside the XRT error circle down to 3sigma limiting magnitudes of H ~ 15.0 and R ~ 17.0. [GCN OPS NOTE(09apr08): Per author's request, the "080309" in the Subject-line and in the body of the Circular was changed to "080409".]
