Coronal hole faces Earth

Sunspot region 2651 remains fairly quiet with only some B-class activity yesterday. It had a small magnetic delta structure yesterday morning but this has decayed leaving not enough magnetic complexity for strong flares. That doesn't mean we should forget about this region as it can still regain some magnetic complexity which would increase the odds of seeing a strong solar flare but for now we should not expect much fireworks from it. But sunspot region 2651 aside, this sunspot region is not our main point of interest in this news article. We have a very familiar solar feature facing our planet right now: a large coronal hole that I'm sure you will recognize from last time around.
