IA. Analysis of Solar Active Regions and Activity from 08/2100Z
to 09/2100Z: Solar activity was very low. Region 978 (S09E26)
produced a B9.4 flare during this perioed.
IB. Solar Activity Forecast: Solar activity is expected to range
from very low to low. C-class activity is likely from region 978.
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field activity
level will increase from quiet to unsettled early on day 2 as a
recurrent coronal hole becomes geoeffective. There is a slight
chance of isolated active periods at high latitudes.
