The third most powerful solar flare ever recorded erupted from the Sun earlier today, and scientists say Earth could feel the effects with communications disruptions and loss of power.

A major geomagnetic storm is expected to happen when it reaches us on October 29th or 30th.

“It was slightly more powerful that the famous March 6, 1989 flare which was related to the disruption of the power grids in Canada,” Dr. Paal Brekke, the European Space Agency SOHO deputy project scientist reported.
