Sun radiation showered the Earth on Thursday, unsettling the geomagnetic field with CME (coronal mass ejection), according to officials at the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center. While geomagnetic disruptions are still possible, strong storms are not readily threatening.
Tuesday, January 7 at 1:32 p.m. Eastern Standard Time, the sunspot on Region 1944 formed the eruption and has shown no signs of decomposition or additional flaring.
Sun and Technology
The ever-changing nature of the sun has made economies around the world more and more vulnerable. Power grids, military communications, civilian communications, high-frequency airlines, and Global Positioning Systems (GPS) signals can all be disrupted by solar flare erupting dangerous radiation into the upper atmosphere blanketing the Earth.
NOAA keeps an eye on solar flares, attempting to predict when sun radiation eruptions will occur, often in time to estimate the amount of radiation showering the Earth. They also work to discover ways to decrease the amount of disruption to space-based technology and the organization will issue warnings when radiation levels reach hazardous levels.
The Solar Weather Prediction Center (SWPC) monitors the sun and solar events with a wide variety of space and ground based imaging and sensor systems to examine the many layers of the sun’s atmosphere. Space forecasters analyze the recurrent 27-day solar activity pattern. Information gleaned from the analysis of current conditions compared with past patterns are fed into weather models resulting in space weather predictions on times scales from weeks to hours.
NOAA is working to minimize the effect of dangerous sun radiation on space-based technology with powerful alerts and warnings: polar grids can be updated, flights can be rerouted and satellites can be adjusted.
Sun Radiation and Global Warming
While the polar vortex sunk the U.S. into sub-zero temperatures, global warming is still a concern despite the recent deep freeze. The last twenty years has brought disturbing climate changes across the globe and raises questions as to why the planet has been turning up the heat, both on land and in the sea. Theories have been tossed about, none of which factor in a human cause. One of the most inescapable theory links sun radiation and global warming. The increasing amount of sun radiation that showers the Earth is in part the cause of the changing climate, but not the only cause.
As the Earth follows its trajectory, it begins to slowly move outside its orbit. These subtle cyclical fluctuations are thought to be the cause of the appearance and the disappearance of the ice age. This natural cooling and heating of the planet is thought to be part of a natural cycle.
The Earth is not alone with a warming and cooling cycle. The sun follows an 11 year pattern of warming and cooling. Radiation from the sun decreases 10 percent during the cooling period cycle. Scientists have theorized the increase in solar flares, sunspots and other solar activities have increased Earth’s temperature variations, and citing sunspot activity at the highest level it has been in a thousand years.
Scientists hypothesize Earth’s temperatures will rise 2-11 degrees by 2100, an increase twice as high as any other climate change in history. Scientists have also determined global temperatures will continue to rise as sun radiation showers the Earth.
