Keivani (Columbia U.), F. Krauss (PSU), and J.P. Osborne (U. Leicester) report:\r\n\r\nSwift observed the field of IceCube 200615A (GCN Circ. 27950) between 08:58:51 UT\r\n2020 June 15 and 11:12:28 UT on 2020 June 16. The observations used\r\n7 pointing directions to tile the inner part of the 90% confidence\r\nregion for the neutrino event. The results of the XRT observations\r\nwere reported by Evans et al. (GCN Circ. 27973).\r\n\r\nUVOT observed the 7 tiling directions using the U filter\r\ncovering a total of ~0.57 deg**2. The UVOT field-of-view is co-aligned\r\nwith the XRT's but is smaller than the XRT's.\r\nWe analyzed the longest exposure for each direction,\r\nwhich ranged from 337 s to 363 s. The averge exposure was 348 s.\r\nNo uncatalogued point sources were found with a\r\ntypical sensitivity limit of 19.0 mag.\r\n\r\nWe also searched for counterparts to the XRT sources reported by\r\nEvans et al. (GCN Circ. 27973).\r\nSources 1, 3, 4, and 6 were detected with UVOT and are\r\nalso in the Digital Sky Survey.\r\nSource 2 was not detected with UVOT.\r\nSource 9 is near a bright galaxy, which was detected with UVOT.\r\nSources 5, 7, and 8 are outside the field-of-view of UVOT\r\nfor all the observations.",
