TITLE: GCN CIRCULAR NUMBER: 29006 SUBJECT: GRB 201209A: FRAM-Auger optical limit DATE: 20/12/09 06:50:15 GMT FROM: Martin Jelinek at Astro.Inst-AVCR,Ondrejov Martin Jelinek, Jan Strobl (ASU CAS Ondrejov, CZ), Martin Masek, Petr Janecek, Sergey Karpov, Jakub Jurysek, Jan Ebr, Ronan Cunniffe, Petr Travnicek and Michael Prouza (Institute of Physics, Prague, CZ) report: The 30cm robotic telescope FRAM-Auger in Malargue (Argentina) reacted robotically to the Swift/BAT alert of GRB201209A (Gropp et al., GCNC 29005), starting with a series of 20 s R-band images at 05:45:40 UT, i.e. 48 s post trigger. We do not detect any new or strongly variable source at or around the reported X-ray error box in single frames nor in a combined 20 x 20 s image spanning the period from 0.8 min to 11.9 min after the initial trigger. The combined exposure has a 3-sigma limiting magnitude R(Vega) ~ 17.4.
