Analysis of Solar Active Regions and Activity from 17/2100Z to 18/2100Z: Solar activity was very low. Region 942 (S12E41) is the only spotted region on the disk. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electrons at GOES were at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days. III.
