High solar activity, coronal hole

Solar activity increased to high levels yesterday as sunspot region 2222 produced an M6.1 solar flare at 18:25 UTC. This was actually one of two M-class solar flares yesterday as the same same region produced an M1.3 solar flare at 08:56 UTC on the same day. Just now as we were writing this news article, sunspot region 2222 released yet another M-class solar flare: M1.5 at 12:25 UTC. Did any of these eruptions launch a coronal mass ejection? We are keeping our attention on the Sun and another solar feature you can't miss right now is a large and dark coronal hole which is located on the Sun's southern hemisphere and directly facing earth right now. Will this coronal hole bring us enhanced solar wind conditions and thus aurora in the coming days?
