Leicester) report \non behalf of the Swift-UVOT team:\n\nWe have observed the area around the Fermi-LAT GRB 141207A (Arimoto et\nal., GCN Circ. 17146), in 4 UVOT fields starting at 07:59:28 UT, 12\nhours and 48 minutes after Fermi/LAT detection. There is an optical source\nat a position of RA,Dec=160.06441, 3.89477, which is\nequivalent to:\n\nRA (J2000)  = 10h 40m 15.46s\nDec (J2000) = +03d 53' 41.2�\n\nwith an uncertainty of 0.1� (radius, 90% confidence).  This source is\n5.6� from the position of the XRT source (Amaral-Rogers and Evans, GCN\nCirc. 17149) and shows up as a marginal detection in the DSS. It is possibly\nunrelated to the burst.  Follow-up observations will be needed to confirm its nature.\n\nThe preliminary u magnitude using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) is 19.91+-0.17.",
