A northern coronal hole is moving towards the sun and will eject a solar wind stream towards earth arriving approx 27th/28th December. Auroras could be visible in the arctic circle after christmas.

Potential for arctic auroras tomorrow december 28th with G1 class magnetic storm.

CIR= co-rotating interaction region, two fields of plasma stream solar wind, one fast, one slow interacting.

CIR's contain plasma shocks and intense magnetic fields that often do a good job sparking arctic auroras.

December 30th: 

Thermosphere climate index:  35.2 billion watts.

Kp index=3=quiet

Solar wind speed 587.2km/sec

Solar wind speed density 9.7 protons cm/3.

The thermosphere temps have risen approx 400 million watts in one week, from observation, estimating that solar wind speed has been above 500km/sec frequently and solar wind density has been reaching almost double figures, also kp index has risen to storm level, one has to assume that these contributing factors have heated the thermosphere a little. Still very cold due to low solar minimum count.

A few called for 220 sunspotless days for 2018, so kudos to those who did.
