Abstract
The corona was photographed at the total solar eclipse of 1952 February 25 with a quadruple camera of focal length 200 cm. Six plates were obtained, each with four corona images, exposed simultaneously, three through polaroids with planes of polarization 60° apart, and one without polaroid. Each plate carried relative and absolute calibrations. An extensive photometry of these plates has provided intensities, amount and direction of polarization, a separation of K and F coronas, and electron densities. The results are summarized in graphs. Comparison is made with van de Hulst's model and with other observations made at the same eclipse.
