This paper discusses the first all-sky surveys of cosmic extreme ultra-violet and soft X-ray sources, discovered by ROSAT. Details of the surveys are presented, with comparisons made to previous selected surveys in the X-ray regime. The subsequent optical identification programs are described, and the major results summarized. We then discuss the main classes of EUV emitters: active chromosphere stars and

In order to operate large telescope, it is crucial to have a good weather forecast especially of the temperature when the telescope begins preparation, i.e., open the dome to introduce new fresh air inside. For this purpose, the Mauna Kea Weather Center (MKWC) has been established in July 1998 by the initiative of Institute of Astronomy, University of Hawaii. The
