The contributions to this work are based on late-1990s knowledge of solar corona physics and on the prospects for future total eclipse observations, focusing on the eclipse of August 11, 1999 - the last this century - which forecasters believe will occur at precisely the maximum of solar activity. The results of past eclipse observations are reviewed, including coronal hot and cold structures, coronal heating, public education and instrumental problems. The relation of the corona to the Sun is discussed, that is, the energy and mass transfer between the chromosphere and the corona, including...
