Following the gamma-ray flare of CGRaBS J1848+3219 (also known as B2 1846+32A and 1FGL J1848.5+3224; Abdo et al. 2010, ApJS 188, 405) detected by Fermi LAT on October 18, 2010 (ATel #2954, Donato et al. 2010) we performed a Swift target of opportunity observation on October 19.
Swift/XRT data were taken in Photon Counting mode for a total exposure of 4.4 ksec. The X-ray spectrum (0.3-10 keV) can be fit by an absorbed power law model with a HI column density consistent with the Galactic value in the direction of the source.
