Geospace Discussion (SWPC) .24 hr Summary... The geomagnetic field was at quiet to active levels. .Forecast... Geomagnetic field activity is expected to be quiet and unsettled on 05 Dec under waning positive polarity CH HSS influence. Quiet conditions are expected to prevail over 06 Dec under a nominal solar wind regime. Late on 07, the onset of a negative polarity CH HSS will likely increase geomagnetic conditions to active levels.
