Events
What has actually happened, as reviewed by NASA analysts: flares, eruptions, storms and particle events, each with the times and instruments on the record.
Flares, geomagnetic storms and particle events cover the last 30 days; coronal mass ejections cover the last 7, because a full month of CME records is a great deal of text for no added meaning on a current-conditions page. Every entry links back to its record in DONKI.
Catalogued solar flares
UnavailableThe DONKI flare catalogue could not be read from NASA DONKI. No value is shown, and none is substituted from anywhere else.
Reason: NASA DONKI could not be reached: The operation was aborted due to timeout
Catalogued coronal mass ejections
UnavailableThe DONKI CME catalogue could not be read from NASA DONKI. No value is shown, and none is substituted from anywhere else.

Catalogued geomagnetic storms
UnavailableThe DONKI geomagnetic storm catalogue could not be read from NASA DONKI. No value is shown, and none is substituted from anywhere else.

Provenance
Every value on these pages is fetched from NOAA SWPC or NASA CCMC and carries the provider's own timestamp. Nothing is simulated, interpolated or filled in: when a provider cannot be reached, the panel says so and shows no number. There is no overall “space weather score” here — the agencies publish scales, and a single figure invented on top of them would be an opinion wearing NOAA's authority.

Solar flare catalogue from NASA DONKI, fetched from https://kauai.ccmc.gsfc.nasa.gov/DONKI/WS/get/FLR?startDate=2026-10-04&endDate=2026-11-03. A curated catalogue updated by analysts through the day, not a live stream; fifteen minutes bounds the delay on a newly-catalogued event without polling a research service every request.
Analyst-curated flare records for the last 30 days, with begin, peak and end times and the associated active region. Curation lags the event, so the most recent hours may be incomplete — an absent flare is not evidence of a quiet Sun.

Coronal mass ejection catalogue from NASA DONKI, fetched from https://kauai.ccmc.gsfc.nasa.gov/DONKI/WS/get/CME?startDate=2026-10-27&endDate=2026-11-03. As for flares. The window is seven days because the full catalogue entry for each CME is large and a month of them would be a quarter of a megabyte for no added meaning on a current-conditions page.
Analyst-identified CMEs from coronagraph imagery over the last seven days. Speed and direction, where present, come from a fitted analysis with real uncertainty; most CMEs are not Earth-directed.

Storms catalogued after the fact, each with the observed Kp values that defined it. A storm in progress may not yet appear here even when SWPC has issued a warning.

Proton events identified in spacecraft particle data. The instrument and energy channel are recorded on each event because a detection in one channel is not a detection in another.
