TITLE: GCN CIRCULAR NUMBER: 4015 SUBJECT: GRB 050922C: NOT optical observations DATE: 05/09/22 22:16:59 GMT FROM: Pall Jakobsson at Niels Bohr Inst Pall Jakobsson (DARK, NBI), Danka Paraficz, John Telting (NOT, La Palma), Johan P. U. Fynbo, Brian L. Jensen, Jens Hjorth and Jose Maria Castro Ceron (DARK, NBI) report: Using ALFOSC on the 2.56-meter Nordic Optical Telescope, we have obtained a 300 s R-band image of the GRB 050922C field (Swift trigger: 156467, GCN#4013 (Norris et al.)). Using a preliminary photometric zeropoint we estimate the following magnitude for the afterglow: R ~ 16.5 @ 1 hour post-burst. The coordinates are: (RA, Dec)(J2000.0) = (21:09:33.083, -08:45:30.2) with a 0.2" error in each coordiante. A finding chart of the field is available at: http://www.astro.ku.dk/~brian_j/grb/grb050922.830/
