Short answer: At the moment the geomagnetic storm activity is ongoing with multiple CMEs affecting Earth, and forecasts suggest elevated levels into the next day or two, with the possibility of continued disturbances beyond that depending on solar wind conditions. For precise, up-to-the-minute timings and expected durations, check active space-weather alerts from official sources. Context and what to watch

• Current status: Space-weather alerts indicate several CMEs launched in the past 24–48 hours are driving strong to severe geomagnetic activity. The latest CME events and associated solar flares have kept the geomagnetic field disturbed in many regions, with watches and warnings evolving as new solar wind data arrive. Expect periods of enhanced activity (auroras visible at lower latitudes if skies are clear) and potential gaps as the solar wind stream transitions.

• Short-term duration: Geomagnetic storm features (main phase and recovery) can last from several hours to a few days depending on the strength and persistence of the driving interplanetary conditions. Historically, main phases often span 2–8 hours, with recovery potentially extending days; for extreme events, the overall disturbed interval can exceed 1–2 days. The recent events are tracking toward a multi-day disturbance given multiple CME arrivals.

• Forecasts you can rely on now:
  • NOAA SWPC space-weather forecasts frequently publish 3-day and shorter outlooks, including expected Kp and storm levels, with watch/warning status updated as new solar wind data arrive. As of the latest updates, elevated storm levels are forecast to persist over today and tomorrow, with possible continuation depending on the arrival and interaction of additional CMEs.

* Regional alerts (e.g., UK aurora forecasts) can provide practical sighting chances and timing, contingent on clear skies.

• Practical impact to expect:
  • Auroras: Potentially visible at lower latitudes than usual if skies are dark and clear, especially in northern regions.

* technology: Geomagnetic disturbances can induce electric currents and show modest impacts on power systems and navigation/communication services during peak periods; usually localized and short in duration but can be noticeable during strong events.

What you can do now

• Monitor authoritative space-weather portals for real-time alerts and the latest 3-day forecasts:
  • NOAA Space Weather Prediction Center (SWPC)
  • UK Met Office space weather alerts
  • Geomagnetic storm aurora alerts from space weather observers
• If you’re planning night-time aurora viewing, prioritize clear, dark skies around polar regions and keep a flexible schedule in the coming 24–48 hours as conditions may change with new CME arrivals.

Direct answer: The geomagnetic storm activity is currently ongoing with multiple CME arrivals driving elevated conditions, and the strongest disturbances are expected to continue into the next day or two, with potential for further activity depending on additional solar wind and CME developments. For the precise duration, expect a multi-day disturbance possible, but real- time updates from official space-weather agencies should be consulted for the exact end time and evolving levels.
