Potential Impacts: Area of impact primarily poleward of 65 degrees Geomagnetic Latitude.
Induced Currents – Weak power grid fluctuations can occur.
Aurora – Aurora may be visible at high latitudes such as Canada and Alaska.
POSSIBLE CME IMPACT ON MAY 10th: A magnetic filament on the sun erupted May 7th, hurling a CME into space. NOAA analysts say it might deliver a glancing blow to Earth’s magnetic field on May 10th. This is a low confidence forecast. Minor geomagnetic storms are possible if/when the CME arrives.
