The gamma-ray blazar PKS 0250-225 (RA: 02h52m47.9s, Dec:-22d19m25s, J2000) was recently reported by the Fermi LAT team to have increased in flux and entered a high state (E>100MeV) (ATEL #1933). In response, Swift observed the source on Feb. 20 2009 for approximately 8.9 ks. Here we report the preliminary results to spectral fits of the Swift XRT data in the 1.0-10.0 keV range. We analyzed the photon counting mode clean event file from the master catalog on HEASARC.
