Blustery Solar Wind Continues
published: Monday, August 22, 2022 20:49 UTC UTC

We saw six hours of moderate geomagnetic storms yesterday, and the disturbed conditions continue today at minor levels.  The storms are being driven by a series of eruptions from the sun arriving at Earth.  We expect these disturbances to last through Friday and into Saturday, primarily at the minor to moderate level.  This should keep the aurora active but at a higher latitude than yesterday.  We'll post updates as we have them.
