Assembling a slide set even as small as this one would have been impossible without the numerous colleagues having provided us with their data, and kindly granted us permission to make use of them. In addition to the people listed below, we also wish to thank J. Beer, T.J. Bogdan, J. Burkepile, A.J. Hundhausen, and B. Lites for help and assistance with various aspects of this project. Unless otherwise noted, all image processing is by P. Charbonneau. The High Altitude Observatory is a division of the National Center for Atmospheric Research, which is sponsored by the National Science Foundation.

Eclipse photographs digitized and processed by A. Lecinski, High Altitude Observatory, National Center for Atmospheric Research (Boulder, CO).
