Siegel (PSU) report on behalf of the Swift team:\n\nSwift-XRT has performed further follow-up observations of the\nground-detected burst GRB 200413B (Tohuvavohu et al. GCN \nCir. 29819), collecting a total of 9.2 ks of Photon Counting (PC) \nmode data between T0+2.1 days and T0+37 days. \n\nThe uncatalogued candidate X-ray source (Source 1) reported \nin Kennea et al. (GCN Circ. 29827) which had also a possible \nUV counterpart (Siegel, GCN Circ. 29912) is still detected in \nXRT at a count rate consistent with the first observations. \nWe thus rule out a possible association with the burst.\n\nThe results of the XRT-team automatic analysis are at \nhttps://www.swift.ac.uk/ToO_GRBs/00021428/\n\nThis circular is an official product of the Swift-XRT team.",
