Coronal hole faces Earth
Solar activity hit low levels yesterday (thanks to a C-class solar flare) but we will likely drop down to very low solar activity today as there are no sunspot regions on the earth-facing solar disk which look like they are complex enough to produce C, M or X-class solar flares. That doesn't mean we are heading into a period of quiet space weather as a large coronal hole is facing our planet today and sending an enhanced solar wind stream towards our planet.
