GCN Circular 9144
C. Guidorzi (U. Ferrara), R. Smith, C.G. Mundell (Liverpool JMU), A. Gomboc (U. Ljubljana), P. O'Brien, N. Tanvir (U. Leicester) on behalf of a large collaboration report: On 2009 April 18 at 03:10:50 UT we observed the Swift GRB 090417B (Sbarufatti et al., GCN Circ. 9135) with the Liverpool Telescope using the SDDS-R filter. From a 6x300 s frame, inside the revised XRT error circle we clearly detect the SDSS galaxy already mentioned by Fynbo et al. (GCN Circ. 9140). At a mid epoch of 12.10 hrs post burst we estimate its magnitude of r'=21.9 +/- 0.3, calibrated with respect to nearby SDSS stars. This value is consistent with that reported in the SDSS catalogue of 21.6 mag. We therefore conclude that this source is not the afterglow of GRB 090417B, while it could possibly be its host galaxy, as already suggested by Fynbo et al. (GCN Circ. 9140).
