More flares, sunspot regions 2268 & 2277, coronal hole

Solar activity remains at moderate levels thanks to four M-class (all R1) solar flares today. Sunspot region 2268 kicked of with an M2.0 solar flare peaking at 00:44 UTC. This event was followed by two more M-class solar flares also from sunspot region 2268 which peaked in rapid succession around 05:45 UTC: M1.6 and M1.7. This event was followed by the strongest solar flare of today thus far: sunspot region 2277 joined the party with an M2.4 solar flare. A lot of solar flares indeed but the bad news is that none of these events looked to have produced a coronal mass ejection. Could we expect more activity from these sunspot regions and what will the southern hemisphere polar coronal hole bring us?
