Nugent (LBNL) report:\n\nWe co-added 78 archival images from the DeepSky* project at Palomar \nObservatory covering the field of GRB 100206A (Krimm et al., GCN 10376). \n  The images were obtained between 2004-2008 from the Palomar-Quest \nConsortium at the Oschin Schmidt telescope.  The limiting magnitude of \nthe stack is approximately R ~ 23 mag.\n\nIn the combined image we detect a faint (R = 21.7 +/- 0.3 mag relative \nto nearby USNO catalog stars) extended source, slightly outside the \ncurrent XRT error circle to its northeast.  The approximate (+/- 1\") \ncoordinates of the source are:\n\nRA = 03:08:39.10, dec = +13:09:29.3  (J2000)\n\nWe suggest this as a potential host candidate of the short-hard burst \nand encourage spectroscopic follow-up.\n\n* http://supernova.lbl.gov/~nugent/deepsky.html",
