Today, June 8, the onset of one of the most powerful magnetic storms in recent times is expected. This was reported by the Laboratory of Solar Astronomy at the Space Research Institute (IKI) of the Russian Academy of Sciences.

Forecast

  • Probability of the storm starting today: 96%
  • Probability that the storm will last more than a day and affect June 9: 85%
  • The storm's intensity could reach G3 (strong)

According to data from the STEREO spacecraft, the plasma cloud ejected by the Sun on June 6 is directed straight toward Earth. Based on calculations, the plasma could reach our planet within 2–3 hours after the report (published at 11:55).

What happened

At the beginning of June, a powerful surge in solar activity was observed. One of the plasma clouds, which was initially not directed at Earth, has changed its trajectory and is now approaching our planet. This is the last in a series of ejections, which will "emerge" near Earth.

Possible consequences

A strong G3-level magnetic storm can cause:

  • Disruptions to satellite navigation (GPS/GLONASS)
  • Radio communication interference
  • Increased strain on power systems
  • Worsening well-being in weather-sensitive individuals

In brief

Today, June 8, a strong magnetic storm of up to G3 level is highly likely (96%) to begin. A plasma cloud ejected by the Sun on June 6 could reach Earth within the next few hours. The storm may last more than a day. This is one of the most significant geomagnetic disturbances in recent times.
