High-Resolution Microwave Observations of the Sun

This is the final technical report for grant AFOSR-89-0147 entitled HIGH-RESOLUTION MICROWAVE OBSERVATIONS OF SOLAR ACTIVITY. This report covers the period from 01 November 1988 to 30 April 1992. It contains the abstracts for twenty four 24 presentations at professional meetings Section II and reprints of seventeen 17 papers Section IV. The twenty four 24 professional presentations included meetings of the American Astronomical Society AAS, the American Geophysical Union AGU, the Committee on Space Research SOSPAR, the International Astronomical Union IAU, and the Union Radio Scientifique International URSI. The Very Large Array VLA and the Arecibo Observatory are the worlds largest radio telescopes, each operated at enormous expense by the National Science Foundation NSF the twenty one 21 successful proposals with these facilities, totaling fifty one 51 days, therefore represent an extremely efficient method of carrying out research by the Air Force Office of Scientific Research AFOSR that essentially funds salaries for Tufts scientists who use these facilities, analyze the data, and publish the results.
