Geospace Discussion (SWPC) .24 hr Summary... The geomagnetic field was quiet. .Forecast... Predominantly quiet conditions are expected on 14 Apr, as influences from an isolated positive polarity CH are no longer likely. Unsettled conditions are expected on 15 Apr due to possible SSBC effects. Active conditions, with a chance for G1 (Minor) storm periods, are likely on 16 Apr due to combined CIR and early CH HSS effects.
