Tonight’s estimated aurora level:
Level 3 – Medium
Auroral activity will be at medium levels. Weather permitting, aurora displays will be visible overhead or on the horizon in Mosjøen (Norway), Oulu (Finland), Luleå (Sweden) and Reykjavík (Iceland).
Geomagnetic activity is expected to increase to quiet to unsettled levels (below G1-Minor) on days one and two (06-07 Nov) due to a weak, negative-polarity CH HSS before returning to mostly quiet levels on day three (08 Nov).
As a side note, and quite strangely, Nasa models say a CME will arrive today. We have no idea what this information is based on, what strength it will be or where it came from. No other space weather sources have anything down at all. It will probably be a very weak glancing blow, but something to be aware of.
