  "body": "M. H. Siegel and D. Grupe (PSU) report on behalf of the Swift/UVOT team:\n\nWe have analyzed 2.3 ks of UVOT data for the IPN-detected burst: GRB\n111222A (Hurley et al. et al. GCN Circ. 12714), from 92.9 ks to 95.2 ks\nafter the  IPN trigger. The data are entirely in the white filter.  We detect a faint\noptical source consistent with the XRT source reported in Grupe (GCN Circ.\n12716) at a position of RA, Dec = 179.22008, Dec = 69.07096 , which\nis equivalent to:\n\nRA (J2000): 11h 56m 52.82s\nDec(J2000): +69d 04' 15.4\"\n\nwith an uncertainty of 0.51 arcsec (radius, 90% confidence). Preliminary\nphotometry using the UVOT photometric system (Breeveld et al. 2011, AIP\nConf. Proc. 1358, 373) shows a white magnitude of 19.34+-0.03.  The magnitude\nis not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.01 in\nthe direction of the burst (Schlegel et al. 1998).\n\nWe note, however, that a source is present at this position in the DSS.  Follow-up\nobservations will be needed to determine if the X-ray/optical source is indeed the\nGRB afterglow.",
