NOAA Issues G3 Storm Watch for June 8 as June 6 CME Targets Earth

3 articles · Updated · spaceweather.gov · Jun 6

Summary

  • A G3 geomagnetic storm watch is in effect for June 8, with a lower G2 watch issued for June 9 as forecasters track incoming solar activity.
  • The watches follow a coronal mass ejection that erupted from the Sun on June 6 and is expected to reach Earth over the two-day period.
  • G3 marks the stronger forecast for the event’s initial arrival, with conditions then projected to ease to G2 the following day.
  • NOAA said updates may follow as the CME’s speed, timing and magnetic orientation become clearer closer to impact.
