Massive Radiation Hurtling Toward Us, But Not To Worry

Just as we Earthlings were trying to adjust to the polar vortex, now comes a CME from the Sun.Massive radiation is now hurtling toward us from the Sun’s Coronal Mass Ejection. According to the science website “How Stuff Works,” CME’s occur when “the fluctuations of the sun’s magnetic fields cause a large portion of the surface of the sun to expand rapidly, ejecting billions of tons of particles out into space [and producing] a magnetic shockwave that extends billions of miles out into space. If Earth is in the path of that shockwave, our planet’s magnetic field will react to the event.”Massive Radiation Hurtling

If there were a spacewalk planned for this week, it would undoubtedly be cancelled. The astronauts on the space station are shielded from most radiation, so they’ll be fine. Here on Earth, the CME may affect communications. Or your plane may be rerouted. But not to worry: You, dear Earthling, should be safe.

“The radiation blast has prompted some airlines to change aircraft routes,” says Joe Kunches, of NOAA’s Space Weather Office in Boulder, Colo. “They are changing their flight plan to ensure continuous communications, i.e., not flying polar but rather more southerly routes.”

When the CME hits (predicted at 4 a.m. Thursday), the Earth’s magnetic field will be disturbed: high-frequency radio, GPS applications, airline routes, possible power grid transients may be affected during the geomagnetic storm.

NASA postponed the Wednesday launch from Virginia’s eastern shore of the Cygnus cargo spacecraft, scheduled to deliver supplies to the International Space Station, because of the radiation and will assess Thursday morning if it can launch in the afternoon.

The good news? CME’s usually produce stunning auroras –  so that’s something to watch for in the northern U.S.
