3rd Eddy Cross Disciplinary Symposium 2022

Jack Eddy with gray hair, smiling

Sun, Earth, Planet, Space, Atmosphere and Ocean–As our planet becomes one among many thousands of known worlds, our needs to understand how Earth’s space and climate react to our variable star grow in urgency.

Geospace response to an extreme solar flare

Solar flare effects on magnetospheric convection and ionospheric potential.
Friday, June 18, 2021

Solar flares—a sudden eruption of electromagnetic radiation at the Sun—are known to have significant impacts on Earth’s upper atmosphere and ionosphere, but their collective effects on geospace as an integrated system have never been examined.

The Sun, The Earth, and Near-Earth Space
