Below you'll find the geomagnetic conditions for the middle and high latitude. These values indicate the probability for at least one 3-hour K index, at the indicated level, for each of the next three days. Active conditions start at a K index of 4, minor storming K index 5 and heavy storming starts from K 6. It's the fastest way to quickly look if a geomagnetic storm might occur. The predictions are updated daily.

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.

Anyone wants to see if there are chances for an auroral display so our site gets lots of traffic. But with higher traffic comes higher server costs. Support our project so we can keep the website online!

Currently we see the effects of the arrival of a Coronal Mass Ejection (CME) at the ACE satellite. The solar wind speed rose with 79.26 km/sec to 455.5 km/sec.

|G2 - Moderate geomagnetic storm (Kp 6.00) - Observers at high latitudes may see some nice periods of visual aurora. The chances for the Middle latitude is still relatively low.|
