Bulletin

The Sun was spotless again. Solar activity was at very low levels and is expected to remain so.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal values and are expected to remain so.

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

Solar wind became slightly more enhanced during the second half of the period. Solar wind speed varied mostly between 365 and 425 km/s, and Bz oscillated between -6 and + 7 nT (DSCOVR). The direction of the interplanetary magnetic field (phi angle) was predominantly oriented towards the Sun (negative sector).

Geomagnetic activity was at quiet to unsettled levels and is expected to remain so during the next few days.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
