D'Elia (ASDC and \nINAF/OAR) report on behalf of a larger collaboration:\n\nWe observed the field of GRB 090926B (Grupe et al., GCN 9935; Morii et \nal., GCN 9943) with the VLT UT1 equipped with FORS2. Seeing was \n0.8-0.9\". Preliminary inspection of the image reveals a faint, slightly \nextended source at a position consistent with the revised XRT error \ncircle (Grupe et al., GCN 9940; http://www.swift.ac.uk/xrt_positions). \nIts coordinates are (0.5\" error):\n\nRA(J2000) = 03:05:13.94\nDec(J2000) = -39:00:22.2\n\nand its magnitude (based on archival zeropoints) is R ~ 23 on 2009 Sep \n27.246 UT (7.97 hr after the GRB). Inspection of the NOT images (Xu et \nal., GCN 9941) reveals a faint nebulosity, with a luminosity level \nconsistent with the VLT measurement.\n\nPresently, it is not clear whether this source is related to the GRB or \nnot. It may be the host galaxy, or the blend of two faint, adjacent \nobjects. Further observations are planned to evaluate its variability.\n\nWe gladly acknowledge excellent support from the ESO observing staff \nduring a busy night, in particular Yuri Beletsky, and Stephane Brillant.",
