Bulletin

Solar activity was at very low levels and is expected to remain so. The visible solar disk returned to spotlessness. A patchy positive polarity coronal hole (CH) is transiting the central meridian.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal levels during the last 24 hours and are expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

Solar wind speed continued its gradual decline from about 430 km/s to its current values near 370 km/s (DSCOVR). Bz varied between -2 and +3 nT. The direction of the interplanetary magnetic field (phi angle) was predominantly directed away from the Sun (positive sector).

Geomagnetic activity was at quiet levels, with an unsettled interval (12-15UT) recorded at Dourbes. Geomagnetic conditions are expected to be mostly quiet, with a chance on an unsettled interval in particular on 9 July if a glancing blow from the 5 July CME would affect the earth environment.

Today's estimated international sunspot number (ISN): 000, based on 15 stations.
