Git your Li'l Arfin' Annie viewin' glasses out, boiz 'n grrlz ... we gon' have ourselves a Coronal Mass Ejection tonite ... ! Don't worry about it takin' out a satellite or two ... we can always put more up there, right ... ? Just sit back 'n do some viewin' while y' utter sentences like 'Oooooooh, the COLORS ... !' ... that'll take y' back to the '60s real fast ...

Solar Tsunami to Strike Earth Tonight

Published August 03, 2010

The Sun's surface erupted early Sunday morning, blasting tons of plasma into interplanetary space -- directly towards the Earth. 

That wall of ionized atoms should hit the planet tonight, say scientists, creating a geomagnetic storm and a spectacular light show and possibly threatening satellites in orbit. 

"This eruption is directed right at us and is expected to get here early in the day on Aug. 4th," said Leon Golub of the Harvard-Smithsonian Center for Astrophysics. "It's the first major Earth-directed eruption in quite some time."

The solar eruption, called a coronal mass ejection, was spotted by NASA's Solar Dynamics Observatory, which captures high-definition views of the sun at a variety of wavelengths. SDO was launched in February and peers deep into the layers of the sun, investigating the mysteries of its inner workings.

"We got a beautiful view of this eruption," Golub said. "And there might be more beautiful views to come if it triggers aurorae."

The sun's activity usually ebbs and flows on a fairly predictable cycle. Typically, a cycle lasts about 11 years, taking roughly 5.5 years to move from a solar minimum, a period of time when there are few sunspots, to peak at the solar maximum, during which sunspot activity is amplified.

The last solar maximum occurred in 2001.

The latest minimum was particularly weak and long-lasting.

The most recent solar eruption is one of the first signs that the sun is waking up and heading toward another maximum.

They said it'll be visible as "Northern Lights" tonight and tomorrow night.
