Abstract : The staff of Geo-Science, Inc. has cooperated and assisted with the staff of the Sacramento Peak Observatory in the solar research programs at the observatory for three years. The fundamental research work included studies of events preceding solar flares such as filament and plage activity, solar surges, and H alpha activity with the goal of increasing the reliability of predicting solar flares. Studies were made of the spectra of rapidly changing solar features, on the amount of Stark broadening of hydrogen lines in solar flares, and of the deviation from the Boltzmann distribution of excited H atoms in solar flares. The electronics research group contributed to the highly specialized instrumentation development at the observatory. These contributions included the design and development of units to aid in the data reduction, control systems for the various spectrograph and coronagraph systems, automatic data collection systems, control systems for the flare patrol program and the development of a Videx system for transmission of solar flare pictures to AFCRL headquarters, and other locations. The staff also participated in one solar eclipse expedition, and designed and tested the spectrograph control systems for two eclipses. (Author)
