Geomagnetic Storm Update

Key Points  

  • A very energetic solar eruption was observed Tuesday afternoon that produced an R3 (strong) radio blackout and a S2 (moderate) solar radiation storm on Earth.
  • The most delayed aspect of a solar eruption is the arrival of the Coronal Mass Ejection (CME) which generally follows a day or two after the solar eruption and can cause a Geomagnetic Storm.
  • The CME is currently affecting earth as of Friday morning.
  • The resulting geomagnetic storm is off to a modest start, with no substantial storming occurring as of Friday morning.
  • It generally takes on the order of 24 hours or more for the full event to transpire, so stronger storming is still possible.
