Power Companies Brace For Solar Storms

Hugh Pickens writes "Three large explosions from the sun over the past few days have prompted U.S. government scientists to caution users of satellite, telecommunications and electric equipment to prepare for possible disruptions over the next few days that could affect communications and GPS satellites, leave thousands without power for weeks to months, and might even produce an aurora visible as far south as Minnesota and Wisconsin. 'The concern is if the electric grid lost a number of transformers during a single storm, replacing them would be difficult and time-consuming,' says Rich Lordan, senior technical executive for power delivery and utilization at the Electric Power Research Institute (EPRI). The largest solar storm in recorded history was in 1859, when communications infrastructure was limited to telegraphs. Some telegraph operators reported electric shocks, papers caught fire, and the Northern Lights appeared as far south as Cuba and Hawaii. The first of the three solar explosions from the sun already passed the Earth on Thursday with little impact and the second is passing the Earth now and 'seems to be stronger.' "We'll have to see what happens over the next few days," says space weather scientist Joseph Kunches. '[The third storm] could exacerbate the disturbance in the Earth's magnetic field caused by the second (storm) or do nothing at all.'"

    The frequency and alarm with which these "OMG!!! Solar storm coming!!!" announcements are made, and the almost total lack of anything perceptibly happening, is quickly becoming a boy-who-cried-wolf situation. It's rather like tornado sirens going off just because there's a nasty storm dropping hail... it happens so frequently that everyone just ignores them, and what good is there in an early warning system if people have been conditioned to disregard it?

      My issue is that Slashdot is "breaking" this story 5 days after National Geographic posted it and days after the storms already past yet the story reads like this is still an imminent event.
