7-Day Extended Outlook

Geomagnetic activity forecast for the next seven days. Based on NOAA SWPC 3-day data and extended modelling. Uncertainty grows beyond day 3.

🛰️

Data Sources

Days 1–3 use NOAA SWPC 3-day geomagnetic forecast. Days 4–7 are extended using Wing Kp model and statistical baselines.

📡

Update Frequency

The 3-day outlook updates every 5 minutes. The extended 7-day model refreshes every hour.

⚠️

Accuracy

Short-range forecasts (1–3 days) are highly reliable. Extended forecasts (4–7 days) are indicative only — solar activity is inherently unpredictable.
