Comparison with the November 3, 1994 Solar Eclipse

The High Altitude Observatory's expedition to Putre, Chile photographed the eclipse. Their beautiful image inspired us to compute an MHD model of the solar corona for Carrington Rotation 1888 (October 10 - November 6, 1994). To perform the calculation, we used photospheric magnetic field data from Wilcox Solar Observatory.

The solar X-ray image is from the Yohkoh mission of the Institute of Space and Astronomical Science (ISAS) in Japan. The X-ray telescope was prepared by the Lockheed Palo Alto Research Laboratory, the National Astronomical Observatory of Japan, and the University of Tokyo with the support of NASA and ISAS.
