BeppoSAX monitored the BL Lacertae object MKN 501 during a very high intensity state. These observations revealed spectacular luminosity and spectral variability (right panel) associated with simultaneous emission at extremely high energy (TeV band). MKN501 is one of only three extragalactic sources detected at TeV frequencies. Courtesy of E. Pian, TeSRE Institute, CNR, Bologna, Italy
