Coronal hole faces Earth
A high speed coronal hole solar wind stream arrived at our planet yesterday from a small equatorial coronal hole but it did not produce much geomagnetic activity here on our planet. While the solar wind speed increased to above 500km/s, the north-south direction of the IMF stayed mostly northward and little geomagnetic activity was observed. The Kp-index never increased above Kp2 yesterday. However, we are soon getting another chance for some nice auroral displays as yet another coronal hole faced our planet yesterday.
Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future
Oulu, Rovaniemi, Sodankylä, UtsjokiKirkenes
Arkhangelsk, Murmansk, Norilsk, Vorkuta
Kiruna, Luleå, Umeå
