solar flare march

A coronal mass ejection is headed for earth:

A massive solar flare that erupted from the sun late Tuesday (March 6) is unleashing one of the most powerful solar storms in more than five years, a solar tempest that may potentially interfere with satellites in orbit and power grids when it reaches Earth. […]

“When the shock arrives, the expectation is for heightened geomagnetic storm activity and the potential for heightened solar radiation,” Kunches said.

This heightened geomagnetic activity and increase in solar radiation could impact satellites in space and power grids on the ground. Some high-precision GPS users could also be affected, he said.

“There is the potential for induced currents in power grids,” Kunches said. “Power grid operators have all been alerted. It could start to cause some unwanted induced currents.”

Airplanes that fly over the polar caps could also experience communications issues during this time, and some commercial airliners have already taken precautionary actions, Kunches said. Powerful solar storms can also be hazardous to astronauts in space, and NOAA is working close with NASA’s Johnson Space Center to determine if the six residents of the International Space Station need to take shelter in more protected areas of the orbiting laboratory, he added.
