Earth’s equatorial ionosphere exhibits significant and unpredictable day-to-day variations in density and morphology. This presents difficulties in preparing for adverse impacts on technological systems even 24 hours in advance.

TIMED/GUVI observed thermospheric column ∑O/N2 depletion in both hemispheres in March 2017.
The author reviews why, after almost 8 decades, we still have a coronal heating problem.
In this study, we present a magnetic conguration of an erupting pseudostreamer observed on April 19, 2015 on the Southwest limb embedding a prominence cavity. The eruption resulted in a relatively wide CME with a round front and prominence core intersected by a sharp plume.
Specified Dynamics Whole Atmosphere Community Climate Model with thermosphere-ionosphere eXtension (SD-WACCMX) simulations are used to investigate the solar migrating semidiurnal tide (SW2) around September equinox at middle to high latitudes in the Northern Hemisphere.
