 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We present preliminary results from a 100 ksec Suzaku observation of 4C 50.55 (IGR J 21247+5058). 4C 50.55 is the brightest broad line radio galaxy in the hard X-ray (>10 keV) band detected with INTEGRAL and Swift, which is located close to the Galactic plane. From a combination of the XIS and HXD, we are for the first time able to obtain simultaneous broad-band spectra of this source. A rapid flux increase by approximately 20% is found in the XIS light curve in the last 20 ksec exposure. The spectra before the flux rise can be well represented by a partially absorbed cutoff power law with a reflection component. The cutoff energy is found to be 46(sup +3)(sub -6) keV (with a photon index of 1.60(sup +0.04)(sub -0.08)), which is lower than that observed in normal AGNs. The variable component shows a softer spectrum than the averaged spectrum, which may contain the jet emission., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574129, レポート番号: JAXA-SP-09-008E},
