US Dept of Defense -- Naval Research Lab Studies Solar Storms:

E-mail Print PDF
Imagine a threat to the global community with the potential to damage communication satellites, interrupt navigation systems, shut down regional power grids, impede oil and gas exploration, expose aircraft crews to high levels of radiation, and endanger the lives of astronauts. That threat exists, but it's not from any well-organized terrorist group. It's from the sun. "Ultraviolet and X-ray radiation and particle emissions from the sun affect the ionosphere and [the Earth's magnetic field] and can cause lots of problems to space and ground assets," explained Russell Howard, an astrophysicist at the Naval Research Laboratory, in a Dec. 21 interview on Pentagon Web Radio's audio webcast "Armed with Science: Research and Applications for the Modern Military." Howard was joined in the interview by George Doschek, head of the Naval Research Laboratory's Solar Terrestrial Branch, who explained that the "solar wind," a stream of charged particles and radiation constantly blowing toward the Earth, is intensified by disturbances in the sun's magnetic field, such as sunspots, solar flares, and coronal mass ejections. "All the activity on the sun is produced when the sun's magnetic field is converted into particle emissions and acceleration, and radiation," Doschek said. He explained that the magnetic field of the sun actually stores energy, which is released in bursts when the structure of the field suddenly changes to a configuration that holds less energy. "When that happens," he said, "we think that the excess energy goes into radiation and accelerating particles." Howard, who holds a doctorate in chemical physics, said the release of electromagnetic radiation in the form of X-rays, ultraviolet rays, and gamma rays, interacts with the Earth's ionosphere. "The ionosphere is an electrically charged layer of the Earth's atmosphere," he said. "It's most important, because it reflects radio waves, and that's what allows us to propagate radio waves around the Earth," said Doschek, who holds a doctorate in physics. Radiation affects the ionized particles in the ionosphere, causing them to absorb radio waves, causing communication fade-outs, he explained.
