Heads up.
There is a strong to extreme geomagnetic storm underway.
There is a possibility that satellite data could be disrupted.
GEOMAGNETIC STORM IN PROGRESS:
A major geomagnetic storm is in progress following the impact of a CME on August 5th around 1800 UT.
Analysts at the Goddard Space Weather Lab say that the CME impact may have strongly compressed Earth's magnetic field, directly exposing satellites in geosynchronous orbit to solar wind plasma. Stay tuned for updates on this aspect of the storm.
