(NEXSTAR) — The sun is deep in its solar cycle, sparking a strong solar flare and geomagnetic storming that could bring the northern lights to parts of the U.S. NOAA’s Space Weather Prediction Center ...

The March equinox arrives this month at a time when the Sun is already in its most active phase in years, setting up a seasonal alignment that solar physicists have long associated with stronger ...

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

A minor geomagnetic storm can still produce a memorable sky. For northern-tier states, that matters on nights when the aurora sits just close enough to the horizon to reward careful timing, dark skies ...

Geomagnetic storms, instigated by disturbances in the solar wind and coronal mass ejections, impart significant energy into Earth’s upper atmosphere. This dynamic input alters the thermospheric ...
