18th March

Tonight’s estimated aurora level:

Level 4 – High

Auroral activity should be at high levels. Weather permitting, aurora displays may be visible overhead or on the horizon in Trondheim (Norway), Vaasa (Finland), Sundsvall (Sweden) and Faeroe Islands.

We have seen the best of the CME, is not likely we will see the extremely high activity/kp levels from last night, which was one of the best nights in the last 10 years! But there could still be enough left in it to provide a show for those around 60°N latitude and up, so kp4 – kp5 a possibility tonight.
