Geomagnetic storms caused by negative polarity, south polar coronal hole high speed stream (CH HSS) reached G1 - Minor levels early Tuesday, February 27, 2018. Solar wind parameters are expected to further increase today and a G2 - Moderate geomagnetic storm warning...
February 27, 2018
An isolated interval of G1 - Minor geomagnetic storm conditions was observed early February 19, 2018, due to the influence of negative polarity coronal hole high speed stream (CH HSS). Solar activity over the past 24 hours was at very low levels. Earth-facing side...
