TITLE: GCN CIRCULAR NUMBER: 11717 SUBJECT: GRB 110213A: THO optical observations DATE: 11/02/13 22:41:33 GMT FROM: Veli-Pekka Hentunen at Taurus Hill Obs,A95 Veli-Pekka Hentunen, Markku Nissinen, Tuomo Salmi and Harri Vilokki (Taurus Hill Observatory, Varkaus, Finland) report: We continued optical observations of GRB 110213A optical afterglow. We used Celestron C14 XLT and SBIG ST-8XME CCD (Taurus Hill Observatory, Varkaus, Finland). The observations were started at 2011-02-13 17:18:32 (UT) and stopped at 2011-02-13 18:24:28 (UT). Three unfiltered and three photometric R observations with 600s exposure times were made. The afterglow was detected at following position RA 02:51:51.41 and DEC +49:16:23.0. The following magnitudes were obtained from the observations using NOMAD1 1392-0071642 (R=15.230) as the comparison: Tmid(s)+T0 Filter Exp (sec) Mag Mag err Limit 44163 unfilt 3x600 19.1 0.2 20.3 46231 Rc 3x600 19.2 0.3 20.1
