A moderate geomagnetic storm was observed globally as the NOAA planetary Kp index reached 6- between 00:00 UTC and 03:00 UTC on September 03. The geomagnetic storm was triggered by enhanced solar wind conditions likely related to ongoing high speed stream influence, possibly combined with a weak arrival of CMEs from Aug 29 â 30. Further minor to moderate geomagnetic storm conditions may be possible in the next 24 hours due to HSS influence and predicted arrival of CME from Sept 01.
