TITLE: GCN CIRCULAR NUMBER: 13888 SUBJECT: GRB 121024A: BOOTES-1B optical detection DATE: 12/10/24 05:03:53 GMT FROM: Martin Jelinek at Inst.Astrophys.Andalucia,Granada Martin Jelinek, Alberto J. Castro-Tirado and Javier Gorosabel (IAA-CSIC Granada) on behalf of a larger collaboration report: "The 0.3m BOOTES-1B robotic telescope located in Huelva (Spain), observed the optical afterglow of GRB 121024A (Pagani et al., GCNC 13886; Klotz et al., GCNC 13887). The observations started 40 minutes after the GRB trigger. The sum of 20 minutes of unfiltered images with a mean integration time 54 minutes after the GRB shows the OT with magnitude roughly 18.2+-0.5."
