Malesani (NBI/Dark) report:\n\nWe are observing the afterglow of GRB 061126 (Sbarufatti et \nal., GCN 5854, Vanden Berk et al., GCN 5856) with the 1.34m \nSchmidt telescope of the Thueringer Landessternwarte \nTautenburg in Germany. Sky conditions are variable, with \npassing clouds.\n\nObservations started at 18:20:41 UT and consist of 600 s R \nband exposures. The initial airmass was 1.47, it is decreasing.  \nThe afterglow is detected on most single frames.\n\nFrom a raw image, we measure the following magnitude in \ncomparison to the USNO-B1 catalog (R1 magnitudes):\n\nR = 21.5 +/- 0.25 at 0.49907 days after the burst.\n\n(Errors are 0.2 mag statistical and 0.1 mag systematic.)\n\nWe find this agrees very well with an alpha = 1 extrapolation of \nthe data of Smith et al. (GCN 5857) and Updike et al. (GCN \n5959).\n\nObservations are continuing as weather permits.\n\nSpectroscopy is encouraged.\n\nThis message may be cited.",
