On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092. This means that the usual aurora on both sides of the plannet will stratch much farther than they normally do. For example Scottland have a chance of seeing Aurora Borialis on the 3rd and 4th of August.
