TITLE: GCN CIRCULAR NUMBER: 9256 SUBJECT: GRB 090426: inspection of SDSS images DATE: 09/04/26 15:42:35 GMT FROM: Paolo D'Avanzo at INAF-OAB P. D'Avanzo (INAF-OAB/Univ. Bicocca), E. Palazzi (IASF-Bo), C. C. Thoene (INAF-OAB), E. Maiorano (IASF-Bo), G. Chincarini (Univ. Bicocca). L.A. Antonelli, S. Piranomonte (INAF-OAR) report, on behalf of the CIBO collaboration: Inspection of archival Sloan Digital Sky Survey images reveals no object near the position of the optical afterglow (Cummings et al GCN 9254, Xin et GCN 9255) of GRB 090426 down to the SDSS magnitude limits. The nearest object is a faint (and apparently extended) source located at the following position (J2000) : RA = 12:36:19.49 DEC = +32:59:05.5 which is about 18" away from the optical afterglow position provided by Cummings et al (GCN 9254). According to the SDSS this object have r = 19.71 ± 0.04 and a photo-z of 0.3. At this redshift the angular separation corresponds to about 80 kpc. Given the large offsets, this object is unlikely to be related with GRB 090426.
