Iceland),\nreport on behalf of a larger collaboration:\n\nWe observed the field of GRB 090417B (Sbarufatti et al., GCN 9135) with\nthe NOT equipped with ALFOSC. Observations were carried out in the B, R\nand i bands.\n\nInside the revised XRT error circle, we find a single source detected in\nall three bands, with approximate magnitude R=21.3 (at mean time Apr\n17.966, 7.84 hr after the GRB).\n\nThe source is also visible in the SDSS and classified as a galaxy.\nPhotometry reveals that the object has approximately the same brightness\nas in the SDSS (in the R band). In the NOT images the object also appears\nextended. The source is thus unlikely to be the afterglow of GRB 090417B,\nalthough it may be its host galaxy.\n\nWe acknowledge excellent support from the NOT staff and observer.",
