FEMA Announces Severe Solar Weather

Text from the 14 Dec Situation Report:

Sunspots Causing Communication Failures

On December 12, 2006 the NOAA observed a solar radiation storm on the
Sun that produced a powerful and fast Earth-directed coronal mass
ejection that is expected to impact the earth around 1:00 EST on
December 14th. The result of this significant geomagnetic storm is a
potential adverse effect on satellite communications, HF and VHF
mid-latitude radio communications, long-line telephone systems,
powergrids (potentially causing blackouts), oil and gas pipelines, as
well as VLF navigation and GPS systems.

A sunspot is a region on the Sun's surface (photosphere) that is marked
by intense magnetic activity. NOAA monitors these occurrences and issues
Space Advisory Bulletins and Space Weather Scales,introduced as a way to
communicate to the general public the current and future space weather
conditions and their possible effects onpeople and systems. The NOAA
Scales describe the environmental disturbances for three types of
events: geomagnetic storms, solar radiation storms, and radio blackouts.
They list possible effects at each level.

This solar storm occurrence is Bulletin #06-4 (severe). For the next
five days we could experience HF radio communication blackouts on most
of the sunlit side of the Earth for one or two hours. Outages of
low-frequency signals could cause minor satellite navigation disruptions
on the sunlit side of the earth.
