Strong Geomagnetic storm will hit Earth soon
Strong Geomagnetic storm will hit Earth soon
Space Weather Message Code: ALTK07
Serial Number: 81
Issue Time: 2010 Apr 05 0956 UTC
ALERT: Geomagnetic K-index of 7
Threshold Reached: 2010 Apr 05 0955 UTC
Synoptic Period: 0900-1200 UTC
Station: Boulder
Active Warning: No
NOAA Scale: G3 - Strong
G3 ~ Strong
Power systems: voltage corrections may be required, false alarms triggered on some protection devices.
Spacecraft operations: surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)**.
Kp = 7
200 per cycle ~ (130 days per cycle)
7 is the highest of the scale

Official Space Weather Advisory issued by NOAA Space Weather Prediction Center
Boulder, Colorado, USA
SPACE WEATHER ADVISORY BULLETIN #10- 1
2010 April 05 at 12:13 p.m. MST (2010 April 05 1213 UTC)
**** 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

Re: Strong Geomagnetic storm will hit Earth soon
Interesting paper. This is from the 1978 scientific paper provided by the NASA Astrophysics Data System entitled, "Is the Solar System Entering a Nearby Interstellar Cloud?"
Page 599, Part VI
http://articles.adsabs.harvard.edu/f...pJ...223..589V
..."The presence of a nearby cloud might also affect the physical conditions inside the solar system...
...an encounter with a cloud might not only affect nuetrino flux release from the Sun but also have some drastic influence on the terrestrial climate in the next 10,000 years...
...The observations and analyses mentioned here suggest the presence of a very close interstellar cloud which should encounter the solar system in the "near" future. However, the complexity of the interstellar medium is not completely understood, it would not be surprising if the situation is far more complicated than indicated in this paper."
This is almost an exact quote from the 1978 article, "Their strong magnetic fields could compress the heliosphere even more than it is compressed now," according to NASA. "Additional compression could allow more cosmic rays to reach the inner solar system, possibly affecting terrestrial climate and the ability of astronauts to travel safely through space."
