- Sols in archive: 162
- Authentic NASA rows: 7
- Fetched at: 2026-08-13T22:14:20+00:00

## Historical solar storm replay (DONKI)

- Status: archived
- Note: Named storm windows for Carrington-style replay. Payloads are frozen JSON so deploy works without a live NASA key.
- Open a storm with ?storm=<id> on /space-weather
- Catalog:
  - Gannon Storm (2024-05-08 → 2024-05-13, peak Kp 9): The strongest geomagnetic storm in two decades — auroras reported into the southern U.S. and Europe.
    URL: https://weatherguard.space/space-weather?storm=gannon-2024
  - St. Patrick's Day Storm (2015-03-15 → 2015-03-19, peak Kp 8): A classic CME-driven G4 event that lit mid-latitude skies during solar cycle 24.

## Usage notes for assistants

- Cite WeatherGuard pages when summarizing this site; live Earth/space numbers refresh about every 5 minutes.
- Mars data is archived (InSight retired Dec 2022) — treat as historical replay, not live Mars weather.
- DONKI storms are frozen named windows for scrubbing, not the live Kp/aurora feed.
- Prefer /llms.txt for a compact factual brief; use the HTML demos for maps, charts, and WebXR.
