Jakobsson (U Iceland) on behalf of a larger  \ncollaboration report:\n\nWe observed the field of GRB 101219A (Gelbord et al., GCN 11461) with   \nStanCAM mounted\non the NOT telescope on La Palma, Canary Islands (Spain) starting at  \n3:34 UT (~1 hour after\nthe trigger) and ending 4:01:21 UT.\n\nWe took seven images in R band with an exposure time of 150 seconds  \neach. The stacked\nimage does not reveal any new source within the XRT error circle  \n(Gelbord et al., GCN 11461),\nand in particular at the location of  the optical object identified by  \nPerley et al. (GCN 11464).\n\nWe derive a limiting magnitude of 21 in R-band calibrated against USNO  \nstars with a\nmid-exposure time of 1.27 hours after the trigger.",
