Markwardt (GSFC/UMD)\nreport on behalf of the Swift Team:\n\nAt 06:12:58 UT, the Swift Burst Alert Telescope (BAT) issued\ntrigger 257213.  The BAT on-board calculated location is \nRA, Dec 266.265, -28.952 which is \n   RA(J2000)  =  17h 45m 04s\n   Dec(J2000) = -28d 57' 05\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed weak emission in \n15-25 keV band.  We note that this position is within 12 arcmin of the\ngalactic center, and the nature of the emission is consistent with\nan X-ray burst.  The GCN system identified this position as X 1745.6-2901. \nHowever, it could be one of many X-ray bursters in the galactic center\nregion.  Swift did not slew to this source because it was sun-constrained. \nNo further observations are planned.",
