Space storm packs late punch, biggest since '04
A strong space weather storm packed a late punch overnight and ended up being the most significant geomagnetic event since 2004, US experts said Friday, warning more disruption was coming this weekend.
The fusillade of radiation from the Sun caused limited power grid upsets, forced airlines to reroute around the poles and sparked vivid displays of the Northern Lights in some parts of the world.
...As the current storm wound down Friday, Rutledge warned there was a potential for more disruptions by Sunday due to a flare overnight from the same region on the Sun, known as 1429, that has been acting up since early in the week.
The solar flare reached a level two out of five and was not as big as Tuesday's flare but it was associated with a coronal mass ejection that Rutledge said would make its way to Earth early on March 11.
"It is going to affect the Earth. It is headed fairly directed at us," he said.
"We believe that it could cause storming levels that could reach the G3 level again. We don't believe it would have maybe quite the sustained intensity that the storm we just got out of had."
