Bülletään

The Sun was spotless. 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 speed declined slightly from its initial values around 450 km/s to vary between 390 and 430 km/s during most of the period (DSCOVR). Bz varied between -4 and + 4 nT. The direction of the interplanetary magnetic field (phi angle) started out variable, but turned to mostly sunward directions (negative sector) after 21UT.

Geomagnetic activity was at quiet to unsettled levels and is expected to remain so during the next few days, as the earth environment may encounter the slightly enhanced wind streams from some small and patchy coronal holes.
