Kp, solar wind and GOES measurements. Solar-wind summaries use NOAA’s primary spacecraft; full tables include all returned spacecraft and energy bands. Null values mean unavailable, not zero.
Last seven days · NASA DONKI research analyses, not operational warnings. Events can be linked without proving Earth impact. Expand a record for analyses, model arrival estimates and related IDs.
Active regions, radio flux and monthly cycle history. These provide context, not a local impact forecast. Negative cycle values are source missing-value markers.
Check the timestamp printed on each image. Images use the browser’s ordinary HTTP cache and may be older than the data above. Aurora maps are model guidance, not a visibility guarantee.
G, R and S describe different effects on a 0–5 scale. A flare is not the same as a CME. Model estimates can change; no local outage is inferred here. Check NOAA for operational guidance.
Data is fetched directly from public sources and saved in this browser; snapshots are reused for up to seven days. While this page is visible, sources refresh when due (5 minutes to 24 hours). Failed requests retain the last saved snapshot. Clearing saved data removes only this page’s data. Offline reopening of the website is not guaranteed.
