Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low. No flares occurred during the past 24 hours and the solar disk was void of spots. IB. Solar Activity Forecast: Solar activity is expected to be very low for the next three days (03-05 December). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the first day (03 December). A gradual increase to unsettled levels with a chance for active periods is expected late on the second day (04 December) and lasting through the third day (05 December) due to a high speed solar wind stream.
