Montage is an Earth Science Technology Office (ESTO) Computational Technologies (CT) Round III Grand Challenge investigation to deploy a portable, compute-intensive, custom astronomical image mosaicking service for the National Virtual Observatory (NVO). Although Montage is developing a compute- and data-intensive service for the astronomy community, we are also helping to address a problem that spans both Earth and Space science, namely how to efficiently access and process multi-terabyte, distributed datasets. In both communities, the datasets are massive, and are stored in distributed archives that are, in most cases, remote from the available Computational resources. Therefore, state of the art computational grid technologies are a key element of the Montage portal architecture. This paper describes the aspects of the Montage design that are applicable to both the Earth and Space science communities.

The Astronomy and Astrophysics National Historic Landmark Theme Study was prepared by the National Park Service for the National Park System Advisory Board as part of the National Historic Landmarks Program. The purpose of the study is to identify the sites, structures, buildings and objects significant in the history of the sciences of astronomy and astrophysics in the United States. Those properties nominated for National Historic Landmark designation in the study will be evaluated by the National Park System Advisory Board, a committee of scholars and other citizens. The Board will then recommend to the Secretary of the Interior the properties, which in its opinion, should be designated as National Historic Landmarks. The decision to designate or not designate a recommended property rests with the Secretary. A complete explanation of the purpose of the National Historic Landmarks Program and regulations of the program can be found in the appendix to the study.

The 155-cm reflector of the Smithsonian Astrophysical Observatory was used for observations of comets and minor planets on 35 nights during October l986- April l987. The distrubution was fairly uniform November-February, but poor weather permitted only 21 observations during March. Table I lists the 423 measurements published (in the MPCs) since the last report, two of them actually made at the very beginning of May l987. Forty-six of the observations refer to comets, 193 to numbered minor planets (numbered, that is, by the end of the semester; only 11 of them refer to minor planets already numbered at the time of the last report), and the remainder to unnumbered minor planets.

The Principal Investigator visited Mt. Stromlo Observatory from September 1961 through June 1962 under the auspices of this contract to make observations of emission-line stars and planetary nebulae in the southern Milky Way which were discovered during a previous research program. Although many phases of data reduction were still not completed by the end of this extension, the work on the planetary nebulae was essentially completed. (Author)
