Sunspot region 2740 has been much less active as it has been decayed the past few days. But that didn't mean it went totally quiet. A minor eruption near the this sunspot region took place around midnight UTC yesterday and launched a faint partial halo coronal mass ejection that could arrive at Earth in a few days from now.
