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 ...

SWPC has issued a G3 (Strong) or greater geomagnetic storm warning valid until 10/2359 UTC. The solar wind environment became strongly enhanced following the arrival of a CME from 08 Oct at around ...

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 ...

While the Aurora Timeline Viewer Product is unavailable, please refer to the official and operational 3-Day Forecast. By comparing the forecast Kp value in the geomagnetic forecast section 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 ...
