23rd October

Tonight’s estimated aurora level:

Level 2 – Low

Auroral activity will be at low levels. Weather permitting, aurora displays may be visible overhead or on the horizon in Bodø (Norway), Sodankylä (Finland), Kiruna (Sweden) and Reykjavík (Iceland).

The geomagnetic field is expected to be at predominantly quiet levels for the remainder of day one (23 Oct) and the first half of day two (24 Oct), before the anticipated arrival of three of the CMEs. Initial geomagnetic impacts of the transients are expected to be in the form of unsettled conditions late on day two and increase to conditions as high as active (less than NOAA Scale G1 (Minor)) in the early periods on day three (25 Oct.)
