NOAA’s Space Weather Prediction Center (SWPC) issued a revised prediction for solar activity during Solar Cycle 25 that concludes solar activity will increase more quickly and peak at a higher level ...

As part of the Space Weather Prediction Center's rollout of our improved website, the content from the Solar Cycle Progression page is being provided in a new way.

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 ...

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 ...

Region 3664 produced yet ANOTHER X-ray flare as it moves beyond the Western solar limb!! This time, it was an X8.7 flare, the largest of this solar cycle! Due to its location, any CME associated with ...

G1 (Minor) to G2 (Moderate) geomagnetic storms are likely on 09 Oct with the arrival of a CME that was associated with a M1.4 flare from Active Region 4549 on 06 Oct. A high chance for additional ...

Coronal Mass Ejections (CME) are anticipated to impact Earth later on 11 November on into 13 November. Therefore, geomagnetic storm Watches have been posted as: G2-Moderate for 11 Nov; G3-Strong for ...
