Solar activity was moderate. Region 1515 (S16W10) remained the predominant flare producer with an M2/Sf flare at 02/2356Z and frequent C-class flares including a C9/Sf at 03/0342Z associated with a 260 sfu Tenflare. This region, classified as an Fkc/beta-gamma-delta, remained large and magnetically complex with delta magnetic configurations within its interior and trailer spots. Several coronal mass ejections (CME) were associated with flare activity in Region 1515, but the bulk of the ejecta was directed southward, out of the ecliptic plane. Region 1513 (N16W22) retained its beta-gamma magnetic configuration and displayed no significant changes during the period. It produced isolated C-class flares including a C8/Sf at 03/1441Z associated with a Type II radio sweep (estimated shock velocity 1064 km/s). No new regions were numbered.

Solar activity is expected to be moderate through the period (04 - 06 July) with more M-class flares expected from Region 1515.

Geomagnetic field activity was at quiet to unsettled levels with active to minor storm periods detected at high latitudes. ACE solar wind data indicated Earth remained within a negative-polarity coronal hole high-speed stream (CH HSS). Wind speeds were in the 504 to 715 km/s range with a gradual decreasing trend. The Bz component of the interplanetary magnetic field was variable in the +4/-4 nT range. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.

Geomagnetic field activity is expected to be at quiet to unsettled levels through the period (04 - 06 July) with a chance for active levels due to persistent CH HSS effects. Recent CME activity from Region 1515 is not expected to significantly disturb the geomagnetic field.
