Solar activity was at very low levels. The Sun was spotless. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar activity is expected to remain at very low levels.

Solar wind speed varied between 380 and 330 km/s, ending the period near 340 km/s (DSCOVR). Bz was near neutral values until midnight, when it started varying between -6 and +6 nT. The interplanetary magnetic field was mostly directed away from the Sun (positive sector) until around 04:30UT when it turned towards the Sun (negative sector), indicative of a possible sector boundary crossing. Quiet geomagnetic conditions were observed, with an isolated unsettled interval at Dourbes (06-09UT).

Geomagnetic activity is expected to continue at quiet to unsettled levels. In response to a weak wind stream associated with a small negative polarity equatorial coronal hole (CH), an active interval is possible on 5 or 6 August. Another wind stream enhancement associated with a small positive polarity equatorial CH may start influencing the earth environment around 7 August, which may result in an isolated active episode.
