RESEARCH DIRECTED TOWARD THE OBSERVATION AND INTERPRETATION OF SOLAR PHENOMENA.
Abstract
Refinements and continued operation of the combination H alpha prominence and green coronal camera provided motion pictures and daily surveys of prominences and corona. The H alpha flare patrol underwent significant improvements, and data acquisition rates were increased. Patrol observers became further engaged in both flare warning and subjective prediction services. Spectrographic observations of the solar corona and transient limb phenomena provided a continuation of routinely observed green and red coronal emission lines as well as a vast collection of special observations of bright limb phenomena. A white-light sunspot camera gave pictures of sunspots, granulation, and fine structure. Various theoretical and analysis studies were undertaken, based on the extensive patrol data, and on data from the Sacramento Peak 16-inch coronagraph and coelostat systems and their auxiliary spectrographs.
