Zhang (PSU) report on behalf of the Swift-UVOT team:\n\nWe have analyzed 4.5 ks of UVOT data for the SuperAGILE-detected burst GRB\n111211A (Lazzarotto et al., GCN Circ 12666), taken 63.5 to 76.6 ks after the\ntrigger.  Data were taken entirely in the white filter.  We confirm the\nuncatalogued source reported by Kann et al. (GCN Circ. 12668), Zhang (GCN\nCirc. 12673) and Kruehler et al. (GCN Circ. 12675).  However, we can not\nconfirm any statistically significant fading at this time.  The UVOT position is\nRA, Dec = 153.09037, +11.20801 which is equivalent to:\n\nRA (J2000): 10h 12m 21.69s\nDec(J2000): +11d 12' 28.9\"\n\nwith an uncertainty of 0.5 arcsec (radius, 90% confidence). Preliminary\nphotometry using the UVOT photometric system (Breeveld et al. 2011, AIP\nConf. Proc. 1358, 373) shows:\n\nFilter         T_start(ks)   T_stop(ks)      Exp(s)         Mag\nwhite             63.5         76.6          4550          19.51+-0.03\n\nThe magnitudes in the table are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 0.05 in the direction of the burst\n(Schlegel et al. 1998).",
