Solar Flare to hit Earth on Thursday Morning 8th March 2012
Mar 8th
One more solar flare due to sun’s eruption occurred and it is the largest of the last five years. The New York Times reports that the coronal mass ejection will hit earth at about 1:30 a.m on Thursday morning. The solar flare is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.
The sun erupted Tuesday evening, and the effects should start smacking Earth around 4 a.m. PST today, according to forecasters at the federal government’s Space Weather Prediction Center. They say the flare is growing as it speeds outward from the sun.
NASA captured a video of the solar flare as it erupted and hurled a “big blob of magnetized material” toward the earth. The AR1429 sunspot region shouts off a solar flare on Sunday and two more yesterday. The AR1429 region is currently pointing almost directly at earth which means that the coronal mass ejection could have a big impact on earth.
Another set of active sunspots is ready to aim at Earth right after this. But for now, scientists are waiting to see what happens today when the charged particles hit Earth at 4 million mph. More >

Biggest solar storm since 2005 to hit Earth
Jan 24th
The sun is to hit Earth with radiation from the biggest solar storm since 2005 with more to come from the fast-moving eruption. There’s a solar Coronal Mass Ejection travelling towards us at 1,400 miles per second. It will hit Earth around 9am Eastern Time, causing fluctuations on the power grid and disruptions to the Global Positioning System.
The solar flare occurred at about 11 p.m. EST Sunday and will hit Earth with three different effects at three different times. The biggest issue is radiation, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center in Colorado.
The radiation is mostly a concern for satellite disruptions and astronauts in space. It can cause communication problems for polar-traveling airplanes, said space weather center physicist Doug Biesecker.
Radiation from Sunday’s flare arrived at Earth an hour later and will likely continue through Wednesday. Levels are considered strong but other storms have been more severe. There are two higher levels of radiation on NOAA’s storm scale severe and extreme Biesecker said. Still, this storm is the strongest for radiation since May 2005. More >
