Holland (NASA/GSFC & USRA)\nreport on behalf of the Swift UVOT team:\n\nSwift has been continuing to monitor the counterpart to\nGRB060614 (Parsons et al. GCN 5252).  The UVOT U band light curve,\nwhich was nearly flat during the period of 2-10 days after the\nburst at U~22.5 (Holland GCN 5281) has faded to U~24.0 +/- 0.7\n(this last point being a 2.7 sigma detection from data taken\nbetween 15-23 days after the burst).\n\nThe timing and shape of the plateau and subsequent decay are\nvery similar to the U band light curve of GRB060218/SN2006aj\n(Campana et al. Nature, in press, astro-ph/0603279).\nAt a redshift of 0.125 (Price, Berger, & Fox GCN 5275),\nthe possible SN component has an absolute U magnitude about\n2 magnitudes fainter than SN2006aj.\n\nWe encourage observations at other wavelengths to determine\nwhether the flattening previously observed (Fynbo et al. GCN 5277;\nCobb & Bailyn GCN 5282) is from the host galaxy or whether a\ncontributing SN component has since faded.",
