Coronal hole faces Earth

Solar activity remains very low (there are no numbered sunspot regions on the earth-facing side of the solar disk today) but 2017 is off to a good start anyway. A large coronal hole is facing our planet today and sending an enhanced solar wind stream towards our planet.

Coronal hole faces Earth

The solar wind speed is finally dropping back down to ambient levels after being enhanced for well over a week. This was of course due to a massive coronal hole. However, we are likely soon going to see yet another uptick in geomagnetic activity because we have a coronal hole facing our planet today.

Merry Christmas!

The coronal hole solar wind stream is subsiding and our Sun has gone to sleep. No sunspot groups are currently visible on the earth-facing solar disk. That means we are in for some quiet space weather in the foreseeable future.

Coronal hole faces Earth

Sunspot region 2615 never really got going again after the two M-class events on 29 November. The sunspot region grew in size the past few days but never regained the magnetic complexity needed for M-class events. A shame as a nice earth-directed coronal mass ejection would have been very welcome during these quiet times. That means we shift our attention to coronal holes once more and guess what... we have a large coronal hole facing our planet today!
