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 … More 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

五人（Toshinori Maihara、Humihide Iwamuro、Makoto Inoue、Takeshi Miyaji和Yukiyasu小林）被派往该方案。Maihara和H.岩室访问了莫纳克亚天文台，观察高空大气的OH气辉发射。这是为日本和夏威夷大学合作开发的OH抑制光谱仪（OH suppressor，OHS）的准备工作。1992年2月7日至9日，他们在莫纳克亚山顶进行了红外光谱观测。OH气辉的波长范围从1到2 μ m从来没有被测量到。目前的观测是在UH2.2米望远镜上用空间减法成功完成的，这使我们感到OHS. M有很大的希望。Inoue和T. Miyaji通过联合JCMT（夏威夷）、SEST（智利）和OVRO（美国）的三个台站，在1毫米波长上进行了VLBI（甚长基线干涉仪）实验。这是第一位专家 ...更多信息 在1mm波长下的分辨率为20 μ sec。在检测到干涉图之前，我们不能确定成功。相关的数据处理将用一个正在建造的新的相关器进行。这一成功将使我们能够以惊人的分辨率进入活动星系核的最深核心。小林对现代天文学的基础设施进行了调查。他参观了世界著名的天文台和研究所，皇家格林威治天文台，皇家天文台爱丁堡，马克斯普朗克研究所fur天体物理学，慕尼黑，塞罗托洛洛美洲天文台，拉西拉ESO天文台和利克天文台。他参观了罗克韦尔科学中心，讨论了最先进的红外探测器和未来的发展前景。日本国家天文台的技术和管理基础落后于天文学先进国家。他正在为日本Na天文台的基础设施建设制定总体规划。少
