TITLE: GCN CIRCULAR NUMBER: 11709 SUBJECT: GRB 110213A: GRAS011 optical observations DATE: 11/02/13 08:10:35 GMT FROM: Veli-Pekka Hentunen at Taurus Hill Obs,A95 Veli-Pekka Hentunen, Markku Nissinen and Tuomo Salmi (Taurus Hill Observatory, Varkaus, Finland) report: GRAS 011 (Global-Rent-a-Scope, Mayhill, New Mexico) CDK20 20 inch (0.51 m) f/6.8 and FLI ProLine PL11002M CCD camera were used to detect GRB 110213A optical afterglow. The observations were started at 2011-02-13 05:39:52 (UT) and stopped at 2011-02-13 06:14:37 (UT). Two unfiltered and one photometric R observations with 600s exposure times were made. The afterglow was detected at following position RA 02:51:51.42 and DEC +49:16:23.7 consistent those given by Cenko S.B. et al. (GCN 11706) to within positional errors. 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 1643 unfilt 600 15.6 0.1 16.9 2306 unfilt 600 15.8 0.1 16.9 3128 Rc 600 15.9 0.2 16.5 A jpg image of the 600sec unfiltered observation is available at the following URL link: http://cutenews.kassiopeia.net/data/upimages/GRB110213A_text.jpg
