(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:
