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. Times are in UTC.

Long term Kp forecast

Below you'll find the daily maximum expected global geomagnetic conditions (Kp) for the coming 27 days. This is the fastest way to quickly find out what kind of geomagnetic conditions are to be expected over the next 27 days. These predictions are updated weekly by the NOAA SWPC. While space weather is hard to forecast so far in advance, this list can be useful to spot when recurrent and reliable solar features like coronal hole solar wind streams become geoeffective again.

Current data suggest that it is not possible to see aurora now at middle latitudes
