Geomagnetic
activity forecast for the period November 13 - 19, 2015
Tomorrow, Fri Nov
13, we expect at most unsettled conditions.
Unsettled conditions are expected
also Nov 14 - 15 when the first
mentioned day (Nov 14) has higher probability
of active episode (local
K-index = 4).
Next day, we expect at most quiet
to unsettled conditions.
