NAM 12: Scientists see solar outburst in exquisite detail

April 21, 2011 Comments off

The largest disturbances to the Earth’s geomagnetic environment occur when it is buffeted by solar material hurled in our direction by explosive changes in the Sun’s atmosphere. These Coronal Mass Ejections or CMEs contain approximately a billion tonnes of ionized gas or plasma and can have a dramatic and damaging impact on everything from satellites to power grids.

Now a team of scientists have used two spacecraft to study these events in unprecedented detail. Graduate student Anthony Williams of the University of Leicester will present their results on Tuesday 19 April at the Royal Astronomical Society’s National Astronomy Meeting in Llandudno, Wales.

Mr Williams and his team used the Heliospheric Imagers (HI) on the Solar TErrestrial RElations Observatory (STEREO) spacecraft to examine the internal structure of an Earth-impacting CME – seen as sunlight scattered from high density blobs of plasma – as it travels outwards from the Sun. They compared this with the internal structure measured in situ by the Read more…

Compass Deviations/Rumble Noises

March 23, 2011 Comments off


I’m reading both threads and it’s getting too much so if the mods don’t mind, I wanted to start a new thread for generalized locations of both phenomenon.

I’m the guy that is doing the Google Map. I’ve got both the compass and rumble noises on the map. Yes, it’s a lot of work. But it’s necessary for my own peace of mind and I suspect others too.

Obviously, there is something going on. We need to map it all first to get a handle on what this is and whether they are related. I’ve seen the compass deviation as well as heard the rumble first hand so I am convinced that neither are “fake”. Each thread is perfectly normal; they descend into name calling pretty quick so I hope we can avoid that. Just the observations.

Please go to the map and if you can manage it use the key below to put your general location on the map. If you can’t manage the map, please u2u me. Or just give us the phenomenon and a general location in this thread. Links to compass instructions are below.

Red balloon= compass off. Blue line connects them. Put degrees off, date, time in the description
Green balloon= compass okay. Green line connects them.
Yellow pushpin= rumble noises. Put the date/time, direction of sound (if you can).

Both of these are odd enough that I feel that we should have an ongoing map of the locations that has both of them on it. We have a world wide reach so we can do this. Compass readings, follow the directions here. Just enter your zip code and Volia’! It even has a handy compass on a map to show you where magnetic north is.

Geologist Predicts Major N. America Earthquake Imminent (Video)

March 16, 2011 8 comments

This is a very interesting interview with Jim Berkland who is an accredited geologist that worked with the U.S. Geological Survey and predicted the 1989 world series earthquake in San Francisco 4 days before its occurrence.  Mr. Berkland explains the correlation regarding the super moon, equinoctial tide, strange animal deaths, and the current seismic window causing the earthquake catastrophes that we have witnessed in Chile, Sumatra, New Zealand, and currently Japan.  My advice is if you are on the west coast and if you are able to-leave.  I am not a fear monger but I do take precaution, especially with all of the accredited reports that are available all over the internet.  Our heart and prayers are going out to all whom are affected by the quakes.

NASA: Huge Solar Flare Jamming Radio And Satellite Signals, Could Affect Electric Grid, Bright Auroras Expected

February 17, 2011 Comments off

According to NASA, a large solar eruption triggered a giant geomagnetic storm that has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days

The calm before the storm. Three CMEs are enroute, all a part of the Radio Blackout events on February 13, 14, and 15 (UTC). The last of the three seems to be the fastest and may catch both of the forerunners about mid to late day tomorrow, February 17. Watch this space for updates on the impending — G2, possibly periods of G3 — geomagnetic storming.
Watch Today’s Space Weather for the most recent activity.

A strong wave of charged plasma particles emanating from the Jupiter-sized sun spot, the most powerful seen in four years, has already disrupted radio communication in southern China.

Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares. NASA’s Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, circled below:

X-flares are the strongest type of solar flare, and this is the first such eruption of new Solar Cycle 24. In addition to flashing Earth with UV radiation, the explosion also hurled a coronal mass ejection (CME) in our direction. The expanding cloud may be seen in this movie from NASA’s STEREO-B spacecraft. Geomagnetic storms are possible when Read more…

Alarming NOAA data, Rapid Pole Shift

January 20, 2011 Comments off


The NOAA National Geophysical Data Center maintains a data set of annual magnetic north pole coordinates going back to the year 1590, derived from early measurements from ships logs to modern day techniques.

Noting that there has been lots of reporting of pole shift lately, to the point where the phenomenon is actually causing real-world issues such as temporary airport closures, a deeper investigation was in order.

After transferring 420 years of north pole position data from the NOAA Geo Data Center, configuring it to fit in an Excel spreadsheet, adding a complicated formula to determine exact distance between 2 sets of latitude-longitude coordinates, applying the formula to each data point in the series, and then finally plotting it all in a visual graph, it is alarming to discover the amount of pole shift just over the past 10 to 20 years.

Here is one very interesting fact…
Since 1860, the magnetic pole shift has more than doubled every 50 years. That is pretty significant.

Magnetic Pole Shift May Close Airports

January 13, 2011 Comments off


The recent changes at Tampa Bay International Airport regarding magnetic pole re-calibration and runway closure, chart alignment and runway number paint, could become a normal procedure for airports across the land. As an example nearby Peter O’Knight Airport is also scheduling similar changes at their facility.

It’s no surprise to many people that the Earth’s magnetic north pole has always wobbled over geological time, but what may be surprising is the speed at which the magnetic north pole has been recently moving and accelerating.

Although the magnetic north pole was first scientifically located in 1831, during 1904 it was discovered that the pole had begun moving to the northeast at about 9 miles a year (15 kilometers). Scientists in 1989 discovered that the pole shift speed was accelerating and had increased to 35 miles a year (56 kilometers), and was heading directly towards Read more…
