Abstract
We present digitized photographs of the white-light solar corona taken during the total solar eclipse of 22-23 November, 1984, on both calib rated black-and-white film and on color film. Conditions on site in Hu la, Papua New Guinea, were exceptionally clear. The color image was us ed to produce an isophotal map of the inner corona, from which a flatt ening coefficient of 0.23 was measured. The black-and-white image was enhanced through a digital radial filter. Our images are the best proc essed images available from the 1984 eclipse and so provide important data for synoptic observations.
