| Research Abstract |
Five persons (Toshinori Maihara, Humihide Iwamuro, Makoto Inoue, Takeshi Miyaji and Yukiyasu Kobayashi) were sent in this program.
T. Maihara and H. Iwamuro visited Mauna Kea Observatory to observe OH airglow emission from the high altitude atmosphere. This is a preparative work for development of OH suppression spectrometer (OH suppressor, OHS), which will be commissioned as a collaborative instrument between Japan and University of Hawaii. They carried out infrared spectroscopic observations atop Mauna Kea from Februry 7 through 9, 1992. The OH airglow in the wavelength regions from 1 to 2 mum have never been measured so far. The present observations were successfully done by a spatially subtraction method on the UH2.2 m telescope, and made us feel strongly promising for the OHS.
M. Inoue and T. Miyaji made an experiment of VLBI (Very Long Baseline Interferrometer) at a wavelength of lmm by combining three stations of JCMT (Hawaii), SEST (Chile), and OVRO (USA). This is the first exper

iment at the wavelength of 1mm, capable of a highest spatial resolution of 20 mu usec. We are not sure of success until the interferogram can be detected. The data reduction of correlation will be made with a new correlator which is under construction. The success will enable us to get an access into the deepest core of active galactic nuclei with a remarkable resolution.
Y. Kobayashi made survey of infrastructures for modern astronomy. He visited the world-wide famous observatories and institutes, Royal Greenwich Observatory, Royal Observatory of Edinburgh, Max Plank Institut fur Astrophysik, Munich, Cerro Tololo InterAmerican Observatory, La Silla ESO Observatory, and Lick Observatory. He visited Rockwell Science Center to discuss the most advanced infrared detectors and the future prospect on the development. The fundamentals of both technology and administration at National Astronomical Observatory, Japan, are behind the advanced countries in astronomy. He is building a master plan for establishment of infrastructures at Na Observatory, Japan. Less
