Active geomagnetic conditions, Coronal hole faces Earth
We are currently seeing enhanced auroral conditions here on Earth. Hard to say what is causing it but the north-south direction of the interplanetary magnetic field has turned southwards which fuels auroral activity. Active conditions (Kp4) have been observed already and minor G1 geomagnetic storm conditions are not impossible. High latitude sky watchers should be alert of possible aurora in the hours ahead.
