Bulletin

Solar activity was at very low levels. Region NOAA 2717 decayed, leaving the Sun spotless. Another active region is just beyond the east limb. This returning region was spotless during the previous rotation, raising the 10.7cm radio flux with a few solar flux units. 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 varied between 350 and 410 km/s (DSCOVR). Bz gradually changed from values near +6 nT at the beginning of the period to -4 nT around 09UT. The direction of the interplanetary magnetic field was variable, ending the period in a positive sector (away from the Sun). Quiet to unsettled geomagnetic conditions were observed.

Geomagnetic activity is expected to continue at quiet to unsettled levels until 4 or 5 August when a weak wind stream associated with a small negative polarity equatorial coronal hole (CH) may start influencing the earth environment. An isolated active episode is then possible.
