ARCTIC AURORAS: "Spaceweather.com warned us of 'minor geomagnetic unrest and auroras around the Arctic Circle' on Jan. 10th--and the forecast was accurate," reports Rayann Elzein of Utsjoki, Finland. "At one point last night, the whole landscape turned green."

Looks like 2020 was knocked to 193.

Nice display this evening in Scotland.

Yes very interesting for what should be cycle 25 starting. Quite an eye opener at the moment.

INTERPLANETARY SHOCK WAVE SPARKS AURORAS: Surprising forecasters, an interplanetary shock wave hit Earth's magnetic field on Jan. 11th. The impact just after 08:30 UT did not trigger a geomagnetic storm. However, strong magnetic fields downstream of the shockfront opened a crack in Earth's magnetosphere. Solar wind poured in to fuel a nice display of Arctic auroras:

Does anyone have Solar Flux data from SC 24 & SC 23 please. I'd like to allow comparison between this and previous...Ta
