IA. Analysis of Solar Active Regions and Activity from 10/2100Z
to 11/2100Z: Solar activity was very low. No flares were observed
during the past 24 hours. The visible solar disk was spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field was quiet to unsettled. Solar wind speeds at
ACE ranged from 580 to 640 km/s, due to the continued presence of a
recurrent coronal hole high speed stream. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the forecast period (12-14 August).
