SEVERE GEOMAGNETIC STORM:

Kp Index is at 9.  A Index is 118.

We are in a catagory G5 Storm.  NOAA's Space Weather
scale indicates the following effects:

Power systems: grid systems can collapse and 
transformers experience damage.

                     
Spacecraft operations: extensive surface charging, 
problems with orientation, uplink/downlink, and 
tracking satellites.

                     
Other systems: pipeline currents reach hundreds of 
amps, HF (high frequency) radio propagation 
impossible in many areas for one to two days, 
satellite navigation degraded for days, 
low-frequency radio navigation out for hours, and 
the aurora seen as low as the equator.

The Proton Monitor on the Solar and Heliospheric 
Observatory is registering solar wind speeds in 
excess of 900 km/s

The wave of solar particles - known as a solar 
proton event - is already four times more intense 
than any other event detected since the launches 
of SOHO in 1995 and ACE in 1997. At mid-afternoon 
(UT) on July 14th, the storm of particles from 
the Sun was still intensifying.
