Schady (MSSL), report on behalf of the Swift XRT team:\n\nThe Swift BAT instrument triggered on GRB050401 at 14:20:15 UT and Swift \nexecuted a prompt slew (delayed by 9 seconds due to an Earth constraint) \n.  The XRT found a bright source located at the following position (based \non 38 counts in 2.5 seconds):\n\nRA(J2000) = +16h 31m 29s,\nDec(J2000) = +02d 11' 14\"\n\nWe estimate an uncertainty of about 6 arcseconds.   This source is located\n42 arcseconds from the BAT position.\n\nWe note that Swift had a solid attitude solution during this observation.\n\nThe XRT reported a prompt raw spectrum that peaks at about 1 keV with a \nroughly power-law shape (based on 328 s of data in Windowed Timing mode).",
