Abstract
This report gives a general description of a photographic instrumentation system designed, built, and operated by Sandia Corporation for photometric observation of selected wavelengths of corona of the total solar eclipse which occurred November 12, 1966. This system was operated aboard a USAF C-135 aircraft flying with the moon's shadow to enhance the chances of optimum observation of the event and was automatically tracked to overcome the instabilities inherent in an airborne platform. The automatic tracking device was a closed-loop, hydraulically actuated servo system with an electro-optic means of error detection. The photographic part of this system consisted of nine cameras of which six operated in the visible spectrum and three operated in the ultraviolet spectrum. In addition to providing photometric data on four individual wavelengths of these two spectra, the cameras obtained polarization data on two of these wavelengths, recorded the performance of the automatic tracker, and obtained documentary event type photographs.
