The sun unleashed the cosmic double whammy late March 6, erupting with two major flares to cap a busy day of powerful solar storms, Space.com reported. One of the flares is the most powerful solar eruption so far this year.
“Super Tuesday? You bet!” joked Joseph Kunches, a space weather scientist with the National Oceanic and Atmospheric Administration (NOAA).
Both of the huge flares ranked as X-class storms, the strongest type of solar flares the sun can have. They followed several weaker, but still powerful, sun storms on Tuesday and came just days after another major solar flare on Sunday night.
“By some measures this is the strongest one since December of 2006,” Kunches explained. Solar activity has already led to an R3 level radio blackout on NOAA’s space weather scale, he explained, a midstrength event on a scale that reaches to R5. Such effects are caused by X-ray emissions from the sun.
The bigger effects will hit the planet over the next 24 hours.
“Power grid operators have all been alerted."

For one thing, geomagnetic storms -- disturbances in the geomagnetic field that surrounds the planet -- should hit the G3 level, midway up the scale. That could lead to surges in power lines (a major problem for power companies) and issues with satellites.
“Power grid operators have all been alerted, as well as the regulatory agencies that all pay attention to this,” Kunches said.
GPS users will also be affected because of the highly charged atmosphere; it’s very possible that certain types of applications will be interrupted, specifically highly precise calculations and the high-frequency communications that airplanes rely upon.
