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 speed was on a mostly declining trend, varying between 370 and 300 km/s and ending the period with low values around 310 km/s (DSCOVR). Bz varied between -4 and +3 nT, being mostly negative since 06UT. The direction of the interplanetary magnetic field (phi angle) was in a predominantly sunward orientation (negative sector).

Geomagnetic activity was at quiet levels, with an isolated unsettled episode recorded by Dourbes during the 15-18UT interval. Geomagnetic conditions are expected to be quiet to unsettled during the next few days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 27 stations.
