" ... Some papers and discussions included in this book even though they were not presented at the meeting. In some respects, therefore, the book is independent of the colloquium. Several papers had been invited long beforehand with the request to publish them as review papers. The lack of a modern textbook on minor planets is keenly felt, and the proceedings of this meeting, with these additions, should provide a good reference book."--Page viii

Students in Advanced Research for Sky Surveillance( Book )

2 editions published in 1997 in English and held by 1 WorldCat member library worldwide

Spacewatch program discovers small bodies (asteroids and comets) in the solar system and analyzes their distributions with orbital parameters and absolute magnitude. Scanning of the night sky is conducted 18-20 nights per month with tbe 0.9-m Spacewatch Telescope on Kitt Peak. About 1200. to 2000 sqare degrees of sky are searched each year to a V magnitude level of 21.3. Spacewatch discoveries support studies of the evolution of the Centaur, Trojan, Main-Belt, and Earth-approaching asteroid populations. Space watch also finds potential targets for space missions, finds objects that might present a hazard of impact on the Earth, provides accurate astrometry of about 30,000 asteroids annually, and recovers comets and asteroids that are too faint for most other observers. This AASERT grant supported several undergraduate students working on upgrades to instrumentation and analyses of date under the supervision of spacewatch engineers and researchers. The opportunity to have young, energetic new members of the group accomplished a great del of work, simulated and exxelerated our research efforts, and enhanced the students' career opportunities
New Research in Sky Surveillance: Interpretation of Low-Luminosity Objects( Book )

2 editions published in 1997 in English and held by 1 WorldCat member library worldwide

The Spacewatch program discovers small bodies (asteroids and comets) in the solar system and analyzes their distributions with orbital parameters and absolute magnitude. Scanning of the night sky is conducted with a charged-coupled device (CCD) imaging detector. About 1200 to 2000 square degrees of sky are searched each year to a V magnitude limit of 21.5 Spacewatch discoveries support studies of the Centaur, Trojan, Main-Belt. and Earth-approaching asteroid populations. These studies provide information about the evolution of these objects and their orbits
Advanced Research In Sky Surveillance: A Search For Low-luminosity Objects( )

3 editions published between 1992 and 1994 in English and held by 0 WorldCat member libraries worldwide

The new CCD was installed. Improvements were made in the software and in the operation and the system is working well. All through the year the telescope has been assigned for eighteen nights per month. Large numbers of main-belt asteroids have been found. It has been found that objects smaller than 2 meters occur two orders of magnitude more frequently that expected from extrapolation of the size-frequency relation of the larger near-Earth objects. The design of the new 1.8-meter Spacewatch Telescope has begun
