Solar activity remains at low levels as we only have one numbered sunspot region on the Earth-facing solar disk. Most of the geomagnetic activity at Earth thus has to come from coronal holes and today we have yet another coronal hole facing our planet.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
