M-class solar flares and active aurora
The Sun is full of surprises. Just when you least expect it she produces two M-class solar flares: M1.1 at 18:37 UTC and a very long duration M2.2 solar flare that peaked around at 21:26 UTC.
Quiet Sun, gusty solar wind
Solar activty has been very low now for a couple of days. There are only three numbered sunspot regions on the earth-facing solar disk and non of them are likely to produce a strong solar flare. That said, we do not need solar flares and coronal mass ejections for enhanced geomagnetic conditions at Earth. Coronal holes can do the same thing and the effects of such a coronal hole high speed stream is exactly what we are experiencing right now!
