NASA DONKI
NASA's open database of solar and space-weather events — flares, coronal mass ejections, solar energetic particle events, and geomagnetic storms — served through CCMC's public web service. CONNECTED: four event catalogues are fetched live and shown at /space-weather/events.

This is NASA DONKI's catalogue entry: what it is, what it serves, and under what terms. It carries no measurement — the live readings from this provider are fetched at request time and shown at /space-weather, each with the provider's own timestamp.
What it provides
- Solar flares
- Coronal mass ejections (CMEs)
- Solar energetic particle (SEP) events
- Geomagnetic storms
- Interplanetary shocks
Limitations
Connected end-to-end since 2026-08-29 through the documented key-less CCMC web service. CCMC states that DONKI's real-time contents “should be considered only as prototyping quality and in research context”, and AsteriaStar repeats that wherever DONKI events appear: it is an analyst-curated research catalogue, not an operational alert service, and curation lags events by hours. An empty catalogue therefore means nothing has been catalogued yet, never that nothing happened.
