Coronal hole faces Earth

Space weather has been relatively uneventful this week. Our Sun is quiet as we are close to solar minimum. No sunspot regions could be found on the earth-facing solar disk this week. We do see two small bright regions on STEREO Ahead but they look small and inactive. When it comes to auroral activity we do see a slight enhancement in the solar wind data right now but the north-south direction of the IMF (Bz) is mostly northward so enhanced auroral activity is unlikely tonight. However, if you follow us on Twitter or have the SpaceWeatherLive iOS/Android app installed you might have received an alert that we have a coronal hole facing our planet today!
