Geospace Discussion (SWPC) .24 hr Summary... The geomagnetic field was mostly at active or unsettled levels. .Forecast... Day 1 (02 Dec) is expected to be at unsettled levels with another positive polarity HSS and possible early influence from the 29 Nov CME. The bulk of the CME is still thought to pass south of Earth and arrive at its closest point on 03 Dec. Active conditions are expected on 03 Dec with the combined effects of the CME and HSS with a chance of observing G1 (Minor) geomagnetic storms. Another HSS will influence Earth on 03 Dec keeping the environment at mostly unsettled levels.
