Space Magnetism and Geomagnetic Observations

On August 7th and 8th, unique events in space weather and geomagnetic activity took place, which may help us to understand the data available to us.  Keep in mind, this web page represents merely the musings of a single individual, and is not a scientific report.

On August 7th I was scanning the Internet Seismic Server graphs for information, as I frequently do.  I notice at about 08:00 UTC that a peculiar long wave pattern was occurring in certain locations around the globe.  These long wave patterns are not unusual, and they come and go on a regular basis, particularly in certain global locations.  The long wave pattern looks something like this:

The above image is taken from the Greenland station.  But certain Russian, Alaskan, South Pole, and other polar stations frequently exhibit this pattern.  Seismometers use a suspended electromagnetic sensor to detect mechanical waves in the Earth.  But changes in the electromagnetic field will also induce a signal, just like the above long wave pattern.  These long wave patterns typically appear under auroras.  So not only is the seismic station recording earth movements, it is also recording electromagnetic disturbances.

These electromagnetic disturbances also appear frequently in Puerto Rico, Venezuela, and near volcanic hotspots.  There are natural electromagnetic disturbances, and there also appears to be manmade electromagnetic disturbances.  The following pattern is a manmade disturbance normal for Norway, indicating that a very strong electromagnetic pulse occurs daily near the seismic station:

Large earthquakes can set the planet to vibrating.  The mechanical vibrations appear in the seismograms as much smaller, but consistent waves.  Here we see the calm before a major quake, and the ringing of the Earth afterward:

The large earthquake above occurred in Vanuatu, but was recorded in Missouri, USA.  The ground was relatively calm before the quake, but vibrated for hours afterward, before calming down again.

It would appear that Pitcairn Island is a very unstable location, which vibrates for long periods of time.  Pitcairn Island is located near the East Pacific rise where the ground is spreading at the rate of over one foot per year.  Note the clearly increased ground motion frequency before the August 7, 2006 Vanuatu quake.

It is easy to see the difference between electromagnetic disturbances and the mechanical disturbances in a seismogram.  The following seismograms are not uncommon for these locations (Beijing China on left, Bilibino Russia on right), indicating a possibly unstable geomagnetic field for these locations on August 8, 2006:

On August 8th, Mayon volcano is preparing for a major eruption in the Philippines.  There seems to always be volcanic activity in the Philippines and this seismogram is normal for the location:


On August 7th, NASA reported a "surprise solar wind stream," which supposedly caused the strong electron disturbance in space and initiated a geomagnetic storm on Earth.  However, there were no notable CMEs from the Sun, nor were there any notable coronal holes, which could initiate a "surprise solar wind."  Yet, on August 8th the Sun's baseline x-ray activity suddenly started showing significant instability.  I have been watching solar x-ray patterns for several years on a daily basis.  It is my intuitive understanding that some solar activity is explained by gamma ray bursts (GRBs) sending gravity waves into our solar system.  

The gravity waves are notable as three or four  regularly spaced sharp spikes occurring in the solar x-ray flux.  Generally, these spikes are followed within the next 18 to 36 hours by recorded gamma ray bursts.  The gravity waves almost always arrive before the gamma ray bursts.

Another important pattern in solar x-ray flux is the large, smooth "bubble."  When the large smooth bubble appears in the graph, it is usually followed by a very powerful solar flare and/or coronal mass ejection.  The image below illustrates both the smooth bubble before a large flare and the gravity wave signature:


But on August 8, 2006, the solar x-ray pattern showed a significant disturbance, suggesting to me that a more local and less organized event affected the Sun.  

It is my guess that the large Interstellar cloud that our Solar system is just now entering (for the next 10,000 years) is responsible for some of the radiations we receive on Earth, and which affect the Sun.

It would seem to me that the "surprise solar wind" is actually a surprise Interstellar wind.  There is no indication that the Sun released any kind of solar wind to cause the August 7th electrical disturbances in space and on Earth.

I want to emphasize again that the information on this page is only hypothetical and based upon my personal experience in observing and contemplating the meaning of the data.
