Solar activity was at very low levels. The earth-facing solar hemisphere was devoid of sunspots. 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 370 and 410 km/s (DSCOVR). Bz was near neutral values, except for the 22UT-04UT interval when it varied between -5 and + 4nT. The interplanetary magnetic field was predominately directed away from the Sun (positive sector). Mostly quiet geomagnetic conditions were observed, with a few unsettled episodes in Dourbes.

Geomagnetic activity is expected to continue at quiet to unsettled levels. A weak wind stream associated with a small negative polarity equatorial coronal hole (CH) may start influencing the earth environment late on 4 or on 5 August. Another wind stream enhancement associated with a small positive polarity equatorial CH may start influencing the earth environment late on 6 or on 7 August. In response to these wind streams, an isolated active episode is possible.
