After rejecting high background time\nintervals, the net exposure time in the EPIC instrument is about 40 ks.\n\nThe X-ray afterglow is detected at a level of (7+/-3)x10^-15 erg cm^-2\ns^-1 (observed flux in the 2-10 keV range). This value is consistent with\nthe late time (t>1 day) flux evolution as a power law with index ~1.9, as\nreported by Tiengo et al. (astro-ph/0305564).\n\nThe X-ray spectrum is well fit by a power law with photon index 2.2+/-0.4\nand absorption <9x10^20 cm^-2.\n\nThis message may be cited.",
