Auroras are predicted Dec 20-22, due to the influences of a recurrent, positive
polarity CH HSS.
This may produce G1 storm conditions. Kp 5 forecast, Kp 4 likely. Alaska and northern Canada be ready for auroras Tuesday night and Wednesday night.
Lights might be seen lower (southern Canada, northern states) if the conditions are good and as forecast.
Dec 19 forecast is Kp 4, however as of this post at 840pm, data is weak. Faint auroras may be seen tonight in the north.
