Solar activity was low. The largest event of the period was a C4/Sf flare from Region 1267 (S17E13). This region developed a small delta in the central spot. Region 1263, an Ekc spot class with a Beta-Gamma-Delta magnetic configuration, lost some penumbral area in its central spots, however it developed new spots as flux began to emerge from its trailer area. SOHO/LASCO C2 imagery observed two slow moving CMEs at 1036Z and 1736Z with the majority of the ejecta directed off the West limb. SDO and SXI imagery showed filament eruptions associated with the events. These CMEs are not expected to be geoeffective.

Solar activity is expected to be low with the continued chance for an M-class flare from Region 1263.

The geomagnetic field was at quiet to severe storm levels. Minor to severe storm periods were seen from 05/2100Z to 06/0600Z. The period started off with solar wind speeds reaching approximately 620 km/s with a total field strength around 28 nT. The Bz component of the magnetic field was south around -20 nT for 2 hours before crossing into a positive region at approximately 05/2211Z. Solar wind speed, density, and total magnetic field strength slowly decreased throughout the period as the effects of the CME passage began to diminish. The period ended with a wind speed around 440 km/s and Bt around 5 nT. The greater than 10 MeV protons above 10 PFU event that began at 04/0635Z, reached a peak flux of 96 PFU at 05/2150Z, and ended at 06/0515Z.

The geomagnetic field is expected to be unsettled to active on 07 August as a recurrent coronal hole high speed stream is expected to become geoeffective. Levels are expected to decrease to quiet to unsettled on 08 August. Mostly quiet conditions are expected on 09 August.
