New Study of Coronal Mass Ejection and Galactic Cosmic Rays

This newly published study has quite a bit of what I call “scientificeez” making it a little difficult to read and understand. Therefore, I am going to give you a short surmise. The study shows that during times of solar minimum, a greater number of galactic cosmic rays are bombarding the Earth. During times of solar maximum, the amount of charged particles emitted by coronal mass ejections, solar flares, and coronal holes buffet or blowout harmful GCRs.

The understanding of which is worse… “solar minimum or solar maximum” is still undecided. However, I thought I would toss you another factor that has yet made the headlines. The Earth’s magnetic field continues to weaken. This ongoing natural occurring cycle is quietly being closely monitored analyzing the effect of rising count of galactic cosmic rays and the weakening of Earth’s magnetic field.

Galactic cosmic ray observation data is closely related to space weather research and to atmospheric phenomena such as sudden stratospheric temperature rise, and is expected to be used in a wide range of fields in the future.

Professor Chihiro Kato of Shinshu University took the lead in acquiring simultaneous observations of the neutron monitor and muon detector at Syowa Station in the Antarctic in order to acquire bridging data. In the polar regions, unlike low latitude regions on Earth, it is possible to observe galactic cosmic rays coming from the same direction with a neutron monitor and a muon detector due to the weaker deflection by geomagnetism.

Space weather research of galactic cosmic rays using ground based observational data from neutron monitors and multi-directional muon detectors, may be missing relative and corresponding data. Since the phenomenon of space weather is on a short-term, days and hours-long time frame; it is meaningful to investigate changes in the flow of galactic cosmic rays for several hours, which requires a total-sky monitor of galactic cosmic rays.

Normally, when the Magnetic Flux Rope (MFR) arrives on Earth, galactic cosmic rays (GCR) density at ground level decreases rapidly, and then turns to increase recovery to the original level during impact on Earth by the MFR. This is known as a *Forbush Decrease . However, during our studies observation the GCR exceeded the original level before the Earth exited the MFR.

By analysis of the Global Muon Detector Network (GMDN) and solar plasma data, the team concluded the high-speed solar wind causes the unusual enhancement of GCR density by compressing the rear part of the MFR locally.

 During cycles of high solar activity such as coronal mass ejections (CME), solar flares and coronal holes, a burst of charged particles spew outward into our solar system; continue through the heliosphere into interplanetary space. In the case of such events, a huge amount of charged particles release along magnetic field lines and twist into tubular-like formation described as a Magnetic Flux Rope (MFR).

*A Forbush decrease is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME). It occurs due to the magnetic field of the plasma solar wind sweeping some of the galactic cosmic rays away from Earth.

BREAKING NEWS: PART-I Galactic Cosmic Rays Reaching Levels Never Before Seen

Today’s article will come as no surprise to the Science Of Cycles reader. There have been several articles SOC published regarding this issue going back to 2012. One of the highly contested questions regarding the pole shift is…’where’ on the time line of this cycle do we stand. I had addressed this question in previous articles. A significant and conveying influence to the makings of a magnetic pole reversal is the inundation of galactic cosmic rays, often referred to as ‘cosmic rays’.

NASA’s most recent study on galactic cosmic ray levels reaching Earth’s atmosphere are the highest ever reported. It is of no coincidence today’s GCR levels correspond with one of the lowest solar minimums observed. This is compounded by the Earth’s magnetic field weakening at a rate nobody saw coming. Researchers estimated the field was weakening about 5 percent per ‘century’, but new data revealed the field is actually weakening at 5 percent per ‘decade’, or 10 times faster than thought.

These GCRs are made up of high energy electrons, positrons, and other subatomic particles, which originate in sources outside the solar system and distributed throughout our galaxy Milky Way; hence the name ‘galactic cosmic rays’. Although periods of high solar activity such as solar flares, CMEs (coronal mass ejections) and coronal holes (solar winds) play a significant role in space and earth weather (including various natural phenomenon such as earthquakes, volcanoes, hurricanes and extreme weather) – studies indicate the periods of solar maximum are usually short-lived hovering around the 11 year cycle.

I propose that both solar rays and cosmic rays have an effect on Earth’s atmosphere, mantle, outer and inner core by generating the expansion and contraction of fluids and gas. Additionally, I suggest it is the more powerful highly energetic charged particles racing at nearly the speed of light which has the greater influence to Earth and all living things. It is the radiation from GCRs which can have – a yet to be determined minimal-or-significant measured effect on all forms of life. I would postulate the most sensitive species exposed to increasing radiation would be the most vulnerable – and in fact a significant number has already reached a point of extinction.
