A daily deterministic and probabilistic forecast, for next three days, of geomagnetic activity. Observed values of Ap and deterministic Ap forecasts are provided, followed by probabilistic forecasts ...
Similar to the bulletins put out by the NWS local forecast offices, SWPC provides Alerts, Watches and Warnings to the public at large about what to expect from Space Weather. These bulletins are ...
Space Weather describes the variations in the space environment between the sun and Earth. In particular Space Weather describes the phenomena that impact systems and technologies in orbit and on ...
A daily deterministic and probabilistic forecast, for next three days, of geomagnetic activity. Observed values of Ap and deterministic Ap forecasts are provided, followed by probabilistic forecasts ...
This is a short-term forecast of the location and intensity of the aurora. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the ...
The Station A and K indices show the fluctuations in the magnetic field, tied to specific geographic locations. The indices have a range from 0 to 9 and are directly related to the maximum amount of ...
This is a prediction of the intensity and location of the aurora borealis tonight and tomorrow night over North America. This product is based on the OVATION model and uses the maximum forecast ...
The K-index, and by extension the Planetary K-index, are used to characterize the magnitude of geomagnetic storms. Kp is an excellent indicator of disturbances in the Earth's magnetic field and is ...
Region 4274 produced an X5.1 flare at 11/1004 UTC. One of the strongest flares of the cycle. More information will follow in subsequent posts. Stay tuned to our website for updates.
An X1.9 flare (R3-Strong) occurred at 01/0249 UTC from a currently unnumbered active region just rotating onto the visible disk in the solar NE (top left). Analysis will be conducted on any CMEs ...
An S4 (Severe) solar radiation storm is in progress. NOAA’s GOES-19 satellite measurements show the ongoing solar radiation storm has intensified to Severe (S4) on the NOAA Space Weather Scales, and ...
G2 geomagnetic storm levels reached, likely associated with a coronal hole high speed stream. Winds exceeding 700 km/s (over 1.6 million mph) have been observed at L1. Monitor our website for updates.
