AURORA WARNING: Geomagnetic activity has increased to G2-levels today. Sky watchers in places like New Zealand, southern Australia, Alaska, Canada and northern US states such as Michigan and Minnesota should remain alert for auroras. The source of this activity is a high-speed solar wind stream flowing from a large coronal hole on the Sun. Solar wind gusts should continue to buffet our planet's magnetic field for days.
