Aurora forecast

Predicted Kp-indices

Below you'll find the expected global geomagnetic conditions (Kp) and those for the middle and high latitudes (K-indices). These values indicate the expected geomagnetic activity for any given 3-hour period for the next three days. This is the fastest way to quickly find out what kind of geomagnetic conditions are to be expected over the next 3 days. The predictions are updated daily by the NOAA SWPC and do not necessarily reflect the predictions made by the SpaceWeatherLive team.

The Wang-Sheeley-Arge model

This model predicts the solar wind speed and the interplanetary magnetic field (IMF) polarity at Earth, two important parameters in predicting geomagnetic activity. The three predictions (red, green and blue dots) are based on data of Wilcox (WSO), Mount Wilson Observatory (MWO) and SOLIS (NSO) solar observatories.

Current data suggest that it is not possible to see aurora now at middle latitudes
The solar wind speed is currently moderately high (616.9 km/sec.)
