1. Geomagnetic activity: "Should the geomagnetic area is active, then the aurora might be brighter and more in the poles. Geomagnetic exercise is pushed by photo voltaic activity and photo voltaic coronal holes and therefore it waxes and wanes with time."
The latest photo voltaic storm induced northern lights farther south than regular on Thursday. They were being seen in many states, such as Idaho.
