Yes, the Northern Lights can be predicted to some extent. The activity level of the Northern Lights depends on many things (of which some are predictable and some are somewhat random), including sunspots, coronal holes, solar flares and geomagnetic activity. If you’re not an astronomer, your best bet is to check the local Aurora forecast – a KP-index number of 3 or higher means you have a good chance of seeing the Lights.
