Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 5 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (13 Aug, 14 Aug, 15 Aug). IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 557 km/s at 12/0415Z. Total IMF reached 9 nT at 12/1641Z. The maximum southward component of Bz reached -9 nT at 12/1908Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (13 Aug) and quiet to unsettled levels on days two and three (14 Aug, 15 Aug). III.
