Klose (TLS Tautenburg) \nreport on behalf of the GROND team:\n\nWe observed the field of the SuperAGILE burst GRB 111211A (Feroci \net al. 2011, GCN #12666) simultaneously in g'r'i'z'JHK with GROND \n(Greiner et al. 2008, PASP, 120, 405) mounted at the 2.2 m ESO/MPG \ntelescope at La Silla Observatory (Chile). Observations\nstarted on December 12, 2011, at 07:50 UT, 8.5 hrs after the GRB. \nThey were performed at an average seeing of 1\".1 and at an airmass \nof 1.4\n\nWithin the 3 arcmin error circle we find one source brighter\nthan the DSS limit, and not seen on the DSS2-red plate or SDSS-r,\nat the following coordinate:\n\nRA (2000.0) = 10:12:21.7\nDecl. (2000.0) = 11:12:30\n\nwith a conservative error of 0.7 arcsec. This is 1.6 arcmin from the \ncenter of the SuperAGILE error circle. We propose this source as the \nafterglow of GRB 111211A.\n\nWe estimate a rough r-band magnitude (calibrated against the SDSS) of \n\nr'(AB) = 19.0\n\nNo obvious fading is detected, though this is not constraining\ngiven the short GROND coverage and the time after the GRB.\nFurther observations are encouraged to check for the expected fading.",
