(GCN Circ 8195), the UVOT-enhanced X-ray position of GRB 080905A has\nbeen improved to RA, Dec = 287.67390, -18.88022 which is equivalent to:\n\nRA (J2000): 19 10 41.74\nDec (J2000): -18 52 48.8\n\nwith an uncertainty of 1.6 arcsec (90% confidence). This position lies\n1.5\" from the optical counterpart identified by Malesani et al (GCN\nCirc. 8190), consistent with that position.\n\nPosition enhancement, using the XRT-UVOT alignment and matching to the\nUSNO-B1 catalogue, is described by Goad et al. (2007, A&A, 476, 1401\nhttp://www.swift.ac.uk/xrt_positions/Goad.pdf), the current algorithm is\nan extension of this method.\n\nThis circular is an official product of the Swift-XRT team.",
