*** STRONG GEOMAGNETIC STORM IN PROGRESS ***

A geomagnetic storm began at 05:55 AM EST Monday, April 5, 2010. Space
weather storm levels reached Strong (G3) levels on the Geomagnetic Storms Space Weather Scale.

The source of the storming is an Earth-directed Coronal Mass Ejection associated with a weak solar flare that occurred in Active Region 1059 on April 3 at 05:54 AM EST. This is expected to be an isolated storm that should subside quickly. Other than the flare and CME erupting on April 3, this active region has not produced any significant activity.

Systems that can be affected include electric power systems, spacecraft operations, high-frequency communications, GPS, and other navigation systems.

Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions. More
