Those who live near Arctic Circle will observe a polar light. The stream of solar wind approaches Earth with a speed up to 700 km/s. The first contact with quickly moving wind is expected on December 7-8 that can make G1 class geomagnetic storms and a polar light in high latitudes.
In the Sun the coronal hole — area where magnetic field is opened is observed, allowing to follow solar wind. As this opening wide, the arising stream of solar wind is also wide. He can influence Earth within several days even after our planet is included into a stream.
