Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was very low. The visible solar disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field was quiet. The solar wind data as measured at the ACE spacecraft indicated signatures of a solar sector boundary crossing between 29/1330Z to 29/1530Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days (30 August - 01 September). III.
