G2 storm, Sunspots, Website addition
The coronal hole solar wind stream packed a punch last Monday as we predicted and caused two 3-hour periods where we reached the moderate G2 geomagnetic storm threshold. The northern lights put on a grand display and were seen from latitudes as low as the Netherlands, Germany and Poland in Europe and the southern lights were seen from Victoria, Australia! Below we have a small selection of images made during the past few days. The header image used in this article was made by Carita Holmberg from Grisslehamn, Sweden.
