Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C1 event observed at 15/0305Z from Region 2109 (S08, L=221). There are currently 2 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 (16 Jul, 17 Jul, 18 Jul). IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 525 km/s at 15/1126Z. Total IMF reached 15 nT at 14/2100Z. The maximum southward component of Bz reached -9 nT at 15/0547Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (16 Jul, 17 Jul) and quiet levels on day three (18 Jul). III.
