Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was very low. New Region 999 (S02E60), an Axx Alpha group, was numbered today. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet to unsettled. The increase in activity is due to a coronal hole high speed stream. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with a slight chance of active to minor storm conditions at high latitudes. III.
