3 Solar Storms to Hit Earth At Almost The Same Time, Power Companies Prepare: NOAA . The Next 6 To 12 Hours Are Critical..
Posted August 5, 2011on:
The 1859 solar storm hit telegraph offices around the world and caused a giant aurora visible as far south as the Caribbean Islands.
Some telegraph operators reported electric shocks. Papers caught fire. And many telegraph systems continued to send and receive signals even after operators disconnected batteries, NOAA said on its website.
A storm of similar magnitude today could cause up to $2 trillion in damage globally, according to a 2008 report by the National Research Council.
“I don’t think this week’s solar storms will be anywhere near that. This will be a two or three out of five on the NOAA Space Weather Scale,” said Kunches.
The NOAA Space Weather Scale measures the intensity of a solar storm from one being the lowest intensity to five being the highest, similar to scales that measure the severity of hurricanes, tornadoes and earthquakes.
The first of the three solar explosions from the sun this week already passed the Earth on Thursday with little impact, Kunches said, noting, the second was passing the Earth now and “seems to be stronger.”
And the third, he said, “We’ll have to see what happens over the next few days. It could exacerbate the disturbance in the Earth’s magnetic field caused by the second (storm) or do nothing at all.”
Power grid managers receive alerts from the Space Weather Prediction Center to tell them to prepare for solar events, which peak about every 12 years, Tom Bogdan, director of the center said.
He said the next peak, called a solar maximum, was expected in 2013.
“We’re coming up to the next solar maximum, so we expect to see more of these storms coming from the sun over the next three to five years,” Bogdan said. (Reporting by Scott DiSavino; Editing by Alden Bentley)

Kp Index 8 – Severe:
Power systems: possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid.
Spacecraft operations: may experience surface charging and tracking problems, corrections may be needed for orientation problems.
Other systems: induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.)**.
