The great American solar eclipse of August 21, 2017 provides a unique opportunity to study the basic physics of the upper atmosphere and ionosphere. While the effects of solar eclipses on the upper atmosphere and ionosphere have been studied since the 1930s, and later matured in the last several decades, recent advances in first principles numerical models and multi-instrument observational capabilities continue to provide new insights. Upper atmospheric eclipse phenomena such as ionospheric conjugate effects and the generation of a thermospheric bow wave that propagates into the nightside are simulated with high-resolution first principles upper atmospheric models and compared with observations to validate this understanding.
