TITLE: GCN CIRCULAR NUMBER: 10839 SUBJECT: GRB 100614A: BOOTES-2/TELMA optical observations DATE: 10/06/14 23:16:03 GMT FROM: Alberto Castro-Tirado at Inst.de Astro. de Andalucia M. Jelinek, A. J. Castro-Tirado (IAA-CSIC Granada), P. Kubanek (IAA-CSIC and IPL-UV) and A. de Ugarte Postigo (OAB), on behalf of a larger collaboration, report: "The TELMA 0.6m robotic telescope at the BOOTES-2 astronomical station in South Spain has responded to GRB 100614A 18s after the GCN notice (and about 6.9 min after the onset of the GRB). The co-add of 36 images (3-s each, unfiltered) obtained through cirrusses provides a R = 18 limiting magnitude at the position of the X-ray atterglow (Stratta et al. GCNC 10837)."
