GRB 241209A: Prompt enhanced Swift-XRT position

Using promptly downlinked XRT event data for GRB 241209A, we find a fading X-ray source with an enhanced position: RA,Dec = 155.39704, 6.32828 (degrees) which is equivalent to: RA (J2000.0) = 10 21 35.29 DEC (J2000.0) = +06 19 41.8 with an uncertainty of 1.9 arcsec (radius, 90% containment). This location is 87.3 arcseconds from the BAT onboard position, inside the BAT error circle. Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/1273071 . Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular is an official product of the Swift-XRT team.
