  "body": "D. Alexander Kann (TLS Tautenburg), Adria C. Updike and Dieter H. Hartmann \n(Clemson University) report:\n\nWe performed astrometry (against the USNO-B1.0 catalog) on the image of \nthe field of GRB 100115A (Cummings et al., GCN 10325) taken by the 0.9m \nSARA observatory at KPNO, which revealed a possible afterglow candidate \n(Updike et al., GCN 10328).\n\nFor this object, we derive a position of (conservative error 1\"):\n\nRA (J2000):    00:13:28.05\nDec. (J2000): -00:49:32.4\n\nin full agreement with the position given for Object \"A\" by Jelinek et al. \n(GCN 10331), and possibly closer to (or identical with) the brighter \nsouthwest component of Object \"A\".\n\nGiven the lack of photometric information in Jelinek et al. (GCN 10331) we \ncannot confirm if the SARA candidate has faded significantly, but note \nthat, in the SARA image, the afterglow candidate is about as bright as the \nstar to the southwest at RA (J2000): 00:13:27.20, Dec. (J2000): -00:49:42.4, and it \nseems to be much fainter than this source (note the different filters, \nthough) in the Jelinek finding chart.\n\nThis message may be cited.",
