Bloom (UC Berkeley) report:\n\n\"We co-added 49 archival images from the DeepSky* project at Palomar\nObservatory covering the field of GRB 101224A (Krimm et al., GCN\n11484). The images were obtained between 2005-2007 from the\nPalomar-Quest Consortium at the Oschin Schmidt telescope.  The 3-sigma\nlimiting magnitude of the stack is approximately R ~ 23.0 mag.\n\nIn the combined image we detect a faint (R = 20.5 +/- 0.2 mag,\npreliminary photometry, relative to nearby USNO catalog stars), near\nthe center of the current XRT error circle (Pagani et al. GCN 11488).\nWe cannot definitely determine if source is extended or not. An image\nof the field may be found at:\n\n   http://lyra.berkeley.edu/~jbloom/grb101224a.pdf\n\nThe brightness of the source appears to be just consistent with the\nUVOT upper limits (Landsman et al.  GCN 11490), especially given the\nrelatively red response of DeepSky imaging versus that of the UVOT.\nThis source may be the (bright) host galaxy or a quiescent counterpart\n(if indeed the source is indeed Galactic in origin). However, further\nobservations are required to establish the connection of this source\nto the GRB.\"\n\n* http://supernova.lbl.gov/~nugent/deepsky.html",
