15th October


Tonight’s estimated aurora level:

Level 3 – Medium

Forecast:
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).

Comments:
At the moment we are relying on CH HSS stream, it is showing signs of weakening, but the affects from the 13th Oct M1.7 flare could arrive as early as tonight, so this could all change in a moments notice. Enhanced solar wind speed and IMF variability are expected to persist for the next three days (15-17 Oct) with a combination of CH HSS and CME effects.
