Scientists present the first direct observations on the rapid evolution of a bright red auroral arc into a thin white-mauve arc known as STEVE.
Amateur radio observations provide a new method for studying large-scale ionospheric disturbances and HF communication impacts, and are important applications in ionospheric space weather monitoring.
To help mitigate magnetic storm interference on electric power grid operations, extreme-value geoelectric fields have been mapped across the mid-Atlantic United States.
Exploring the relationship between solar extreme ultraviolet radiation flux and 150-km radar echoes.
A new modeling effort could change our understanding of auroral arc formation.
