Magnano (INAF-IASFPA) report on behalf of\nthe Swift/UVOT team:\n\nThe Swift/UVOT began observations of the field of GRB101201A\napproximately 14 hours after the BAT detection (GCN Circ. 11429).\nWe confirm the uncataloged source reported Guelbenzu et al.\n(GCN Circ. 11430).  We also find evidence of fading between\nthe two orbits.  Magnitudes for the first and second orbit exposures\nare listed below.\n\nFilter         T_start(s)   T_stop(s)      Exp(s)         Mag\n\nwhite            52065        52087           21         19.90+-0.49\nwhite            57847        58387          531         20.01+-0.11\nu                51218        52058          827         19.50+-0.17\nu                57000        57840          826         20.01+-0.26\n\nThe above magnitudes are not corrected for the Galactic extinction\ncorresponding to a reddening of E_{B-V} = 0.02 (Schlegel et al.,\n1998, ApJS, 500, 525).
