Coronal hole, Aurora forecast page

Solar activity is very low today and expected to remain so in the foreseeable future as no sunspot regions on the earth-facing side of the solar disk are complex enough to produce C, M or X-class solar flares. Sunspot region 2638 did gave us a few C-class solar flares during the past few days but it is not a sunspot region to get really excited about. That means we have to shift our attention (like we've been doing for quite some time now) to another solar feature that we've all become very familiar with: coronal holes. Today we have such a coronal hole facing our planet and it is now sending an enhanced solar wind stream towards our planet that is expected to arrive within the next 48 to 72 hours.
