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
