****************************************************** PR # 31208 GRS1227+025 is a hard-xray source discovered with SIGMA telescope dur ing its observation of 3c273. The source is apart from 3c273 by 15 ar cminutes, and its flux at 40-80kev band was as bright as 3c273. There are several soft X-ray sources within the SIGMA error box of GRS1227 +025, however, those are hudreds times weaker than 3C273. It means i f one of them is the counterpart of GRS1227, it has extraodinary hard spectrum, e.g. heavily absorbed power law spectrum or so. With ASCA, we would observe the sky including error-box of GRS1227+025 to see i ts nature in medium energy X-ray band. ******************************************************
