Default WARNING: Geomagnetic K-Index of 6 expected -- Valid From: 2012 Mar09 0330 UTC

Space Weather Message Code: WARK06
Serial Number: 187
Issue Time: 2012 Mar 09 0319 UTC

WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2012 Mar 09 0330 UTC
Valid To: 2012 Mar 09 0900 UTC
Warning Condition: Onset
NOAA Scale: G2 - Moderate

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/NOAAscales

Potential Impacts: Area of impact primarily poleward of 55 degrees
Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude
power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased
drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washinton
state.

An astronomer would take a different view of these events,while
earthquakes have tragic consequences and often destroy human
settlements,they also indicate the forces at work,not just locally but
in the overall context of evolutionary geology of a global and
astronomical scale.What is experienced locally is actually a signature
of the rotating dynamics of the interior with observational evidence
drawn from looking at exposed rotating viscous compositions.

These 'solar storms' provide the equivalent of a dusting of iron
filings on a global scale and using planetary comparisons with Venus
which has residual rotation,another clue to the rotation of the
Earth's differential rotation emerges -

The original empiricists would have been on to this straight away had
they the information however when I see the science journals and the
way investigators have to continuously quote and reference other
works,the overall global and astronomical view is either lost or never
gets going.If I have the freedom to explore in isolation,the drawback
is an unstructured development of an idea and this can be frustrating
as it means having to keep an approach front and center whereas once
should be enough.
