Swift follow-up of the flaring BL Lac 1ES0806+524
Abstract
Following the gamma-ray, VHE (E>100 GeV) flare of the blazar 1ES 0806+525 (RA:08h09m49.2s DEC:+52d18m58.2s, z=0.138) detected by MAGIC on 2011 February 25 (ATel #3192), we performed a Swift target of opportunity observation starting on February 26. Swift monitored the source in photon counting mode with 5 daily observations for a total exposure of 10 ksec. The X-ray spectrum (0.2-10 keV) is well described by an absorbed power law model with a photon index of 2.4+/-0.1 and HI column density fixed to the Galactic value nH=4.1E20 cm-2 (Kalberla et al.
