Using promptly downlinked data we find an\nuncatalogued X-ray source located at RA, Dec 163.66560, 69.06574 which\nis equivalent to:\n   RA(J2000)  = 10h 54m 39.74s\n   Dec(J2000) = +69d 03' 56.7\"\nwith an uncertainty of 3.7 arcseconds (radius, 90% containment). This\nlocation is 94 arcseconds from the BAT onboard position, within the BAT\nerror circle.\n\nA power-law fit to a spectrum formed from promptly downlinked event\ndata gives a column density consistent with the Galactic value of\n1.8e+20 cm^-2 (Kalberla et al. 2005).",
