The Indiana Asteroid Program was a program of photographic asteroid observations made with a 10-inch ''f/''6.5 Cooke triplet astrographic camera〔Thomas Gehrels, ("The Indiana Asteroid Program," ''Astronomical Journal'', v. 63, No. 1256 (February 1958), p. 50. )〕 at Goethe Link Observatory near Brooklyn, Indiana.〔(Indiana University Department of Astronomy: Frank Edmondson Home Page )〕 The program was initiated by Frank K. Edmondson of Indiana University in 1949 and continued until 1967.〔 (Asteroids II Machine-Readable Data Base - Version March 1988, Binzel, R.P. et al., eds. 1989, Univ. of Arizona Press, Note 103: )"Planets discovered by the Indiana Asteroid Program, Goethe Link Observatory, Indiana University. This program was conceived and directed by F. K. Edmondson; the plates were blinked and measured astrometrically by B. Potter and, following her retirement, by D. Owings, and the photometry was performed under the direction of T. Gehrels. During the years 1947-1967, in which the plates were exposed, a large number of people participated in various aspects of the program." 〕 It had four objectives: * recovering asteroids that were far from their predicted positions * making new orbital calculations or revising old ones * deriving magnitudes accurate to about 0.1 mag * training students.〔Tom Gehrels.〕 When the observatory's 36-inch (0.91-meter) reflecting telescope proved unsuitable for searching for asteroids, postdoctoral fellow James Cuffey arranged the permanent loan of a 10-inch (0.254-meter) lens from the University of Cincinnati.〔Ken Kingery, ''Betting on a Sure Thing: A "Record" Ending to Indiana Asteroid Program,'' Indiana Alumni Magazine, v.1, no. 2, September/October 2008, Bloomington, IN: Indiana University Alumni Association, p. 46; See also, (Space Daily ).〕 Mounted in a shed near the main observatory, the instrument using the borrowed lens was responsible for all of the program's discoveries.〔''Id.''〕 By 1958, the program had produced 3,500 photographic plates showing 12,000 asteroid images and had published about 2,000 accurate positions in the ''Minor Planet Circular''.〔 When the program ended, it had discovered a total of 119 asteroids. The program's last unnamed discovery, 30718 Records, made in 1955, was not named until 2008, when its orbit was finally calculated and confirmed.〔News Release, April 7, 2008: IU Asteroid Program "records" final chapter (). The name was chosen by Frank Edmondson in honor of Brenda Records who managed the Indiana University Astronomy Department's office for 20 years.〕 The program ended when the lights of the nearby city of Indianapolis became too bright to permit the long exposures required for the photographic plates.〔Kingery, p. 47.〕 The program's nearly 7,000 photographic plates are now archived at Lowell Observatory.〔Kingery, p. 47, and (Indiana University Department of Astronomy: Frank Edmondson Home Page )〕 == Asteroids discovered by the Indiana Asteroid Program == ''Source: IAU Minor Planet Center: Discovery Circumstances of Numbered Minor Planets'' 〔(IAU Minor Planet Center: Discovery Circumstances of Numbered Minor Planets )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Indiana Asteroid Program」の詳細全文を読む スポンサード リンク
