IA. Analysis of Solar Active Regions and Activity from 30/2100Z
to 31/2100Z: Solar activity was very low. New Region 1025 (N17E33)
was assigned today. No flares were observed.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was quiet to unsettled. The unsettled
conditions were due to a coronal hole high speed stream.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on days 1 and 2 (1 - 2 September). Day 3 (3
September) is expected to increase to quiet to unsettled levels due
to a recurrent coronal hole high speed stream.
