Discovery of VHE emission from PKS 0447 439 with H.E.S.S. and MWL studies

Very-high energy (VHE) emission has been detected from PKS 0447-439 with the H.E.S.S. Cherenkov telescope array. This blazar is one of the brightest hard-spectrum extragalactic objects in the Fermi bright source list. Its detection with H.E.S.S. triggered Target of Opportunity observations with the Swift and RXTE telescopes, which show rapid flaring in the X-ray band. The spectrum and light curve measured by H.E.S.S. are presented. Along with the Fermi LAT data it is possible to put an upper limit on the redshift of the source. Implications of the flux evolution are discussed briefly.
