Here we present several enhancements to our basic prediction for the struture of the solar corona during the solar eclipse. The first movie/image on the left shows the brightness of polarized white light in the corona, processed with a Newkirk radial filter. This is a rough attempt at approximating what the human eye might see during the solar eclipse. The middle column summarizes a digital processing of these images to bring out certain features: The combination of log-scaling and unsharp masking brightens faint features while enhancing edges. On the right, a wavelet high pass filter sharpens fine scale features throughout the corona, showing streamer edges, bright loops, and non-radial features. Although the original images seem quite diffuse, these enhancements bring out the underlying complexity of the plasma and magnetic field distribution in the model.
