NASA Solar Dynamics


NASA Solar Dynamics Photos

This handout image provided by NASA, taken Sunday night, Jan. 22, 2012, shows a solar flare erupting on the Sun's northeastern hemisphere. Space weather officials say the strongest solar storm in more than six years is already bombarding Earth with radiation with more to come. The Space Weather Prediction Center in Colorado observed a flare Sunday night at 11 p.m. EST. Physicist Doug Biesecker said the biggest concern from the speedy eruption is the radiation, which arrived on Earth an hour later. It will likely continue through Wednesday. It's mostly an issue for astronauts' health and satellite disruptions. It can cause communication problems for airplanes that go over the poles. (AP Photo/NASA)

The strongest geomagnetic storm in more than six years was forecast to hit Earth's magnetic field on Tuesday, and it could affect airline routes, power grids and satellites.A coronal mass ejection - a big chunk of the Sun's atmosphere - was hurled toward Earth on Sunday, driving energized solar particles at about 5 million miles an hour (2,000 km per second), about five times faster than solar particles normally travel, the center's Terry Onsager said."When it hits us, it's like a big battering ram that pushes into Earth's magnetic field," Onsager said from Boulder, Colorado. "That energy causes Earth's magnetic field to fluctuate."
