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 computed polarization brightness from an MHD simulation of Carrington rotation 1888. The view corresponds to the approximate time of the eclipse (Carrington longitude of 40 degrees) with the same orientation as the eclipse image above. Click image for high resolution GIF (21 Kbytes).
