GCN Circular 18554
Martin Jelinek (Astronomical Institute ASU-AVCR Ondrejov), Michael Prouza, Jan Ebr, Petr Janecek, Martin Masek (Institute of Physics FZU-CAS Praha) and Samantha Oates (IAA CSIC Granada + UCL MSSL) "The 0.30m robotic telescope FRAM located in Malargue, Argentina, observed the reported location of GRB 151029A (Ukwatta GCNC 18522) starting 884s after the corrected trigger time (Barthelmy GCNC 18535), 8.9s after receiving the trigger. The telescope obtained a 30 minute set of unfiltered exposures. The optical afterglow (Oates GCNC 18531, Knust GCNC 18523, Tanvir GCNC 18524) can be detected on combined exposures. In the first combined image, with the mean time of individual exposures 08:07:27 UT (1068s post trigger), we measure magnitude 17.7 +/- 0.2. The calibration was done with three nearby USNO-B2.0 stars."
