Fynbo,\nP. Jakobsson, J. M. Castro Cerón, H. Pedersen (NBI), report:\n\n\"We have performed almost daily R-band monitoring of the XRF 050509c\nfield (GCN Circ. 3402, HETE-2 trigger #3751) from May 15 to June 8.\nNo significant rebrightening brighter than R ~ 22.5 has been detected at\nthe afterglow position (GCN Circ. 3425) during the mentioned period.\n\nIf XRF 050509c was related to a supernova similar to SN 1998bw, our\nobservations would impose a lower redshift limit of z > 0.4.\n\nA combination of all late images \n(www.astro.ku.dk/~brian_j/grb/grb050509.95/)\nreveals a faint (R ~ 24) object coincident with the afterglow position,\nwhich we tentatively identify as the host galaxy of XRF 050509c.\"",
