****************************************************** PR # 43028 4C 74.26 is the largest of the only two known quasars associated with a giant radio source. It exhibits extreme properties in all wavebands which so far cannot be atttributed to any special physical or environmental conditions of the source.. The ROSAT PSPC spectrum is unusually flat for a radio-loud quasar and cannot be determined well due to the PSPC's narrow energy range, limited spectral resolution, and the high Galactic absorption. A detailed study in a 20 ks ASCA observation will allow the reliable determination of its X-ray spectral properties and will thus enable us to pin down the physical and geometrical conditions of the central emission region of this unusual quasar. ******************************************************
