...A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth's magnetic field on Jan. 24-25 as it sails mostly north of our planet," SpaceWeather’s bulletin read.
It could also affect navigation and the power grid.
The solar flare spat out late Sunday, Jan. 22, at 10:59 p.m. EST was rated an M9-class eruption -- nearly an X-class flare, the most powerful type of solar storm.
NASA spokeswoman Kelly Humphries told Space.com the six spaceflyers currently living and working on the orbiting outpost are not in any danger.
"The flight surgeons have reviewed the space weather forecasts for the flare and determined that there are no expected adverse effects or actions required to protect the on-orbit crew," Humphries told SPACE.com in an email.
