'Dramatic' Solar Flare Could Disrupt Earth Communications

An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.
The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.
"This one was rather dramatic," said Bill Murtagh, program coordinator at the NWS's Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 am Eastern time in the United States, or 0541 GMT.
"We saw the initial flare occurring and it wasn't that big but then the eruption associated with it -- we got energy particle radiation flowing in and we got a big coronal mass injection," he said.
"You can see all the materials blasting up from the Sun so it is quite fantastic to look at."

Since Internet connection is already slow and the phone at home never works, so I guess I would never know whether such things really happen. Too bad.

The Space Weather Prediction Centre said the event is 'expected to cause G1 (minor) to G2 (moderate) levels of geomagnetic storm activity tomorrow, June 8, beginning around 1800 GMT.'
Any geomagnetic storm activity will likely be over within 12-24 hours.
'The Solar Radiation Storm includes a significant contribution of high energy protons, the first such occurrence of an event of that type since December 2006,' the NWS said.
As many as 12 satellites and spacecraft are monitoring the heliosphere, and one instrument in particular on board NASA's lunar reconnaissance orbiter is measuring radiation and its effects.
'Certainly over the (two-year) lifetime of the mission this is the most significant event,' said Harlan Spence, principal investigator for the cosmic ray telescope for the effects of radiation, or CRaTER.
'This is really exciting because ironically when we were developing the mission initially we thought we would be launching closer to a solar maximum when these big solar particle events typically occur,' Spence told AFP.
'Instead we launched into a historic solar minimum that took a long, long time to wake up,' he said.
'This is interesting and significant because it shows the Sun is returning to its more typical active state.'
