Short summary
We present large scale changes to the ionosphere that were observed over a large portion of the continental US from 200 – 450 km altitude during the April 2024 solar eclipse. We observed a decrease in electron density of 50 %, and in electron and ion temperatures of 40 % and 20 % respectively. Unique features included lower densities and temperatures north of the eclipse path as compared to the south, and drops in ion temperature of of 225 K which is among the largest reported during an eclipse.
