Bulletin

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 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 varied between 300 and 325 km/s (DSCOVR). Bz undulated between -4 and +3 nT, with stretches (up to several hours) of mildly negative values. The direction of the interplanetary magnetic field (phi angle) was mostly in a sunward orientation (negative sector), being in a positive sector during some brief intervals.

Geomagnetic activity was at quiet to unsettled levels. Geomagnetic conditions are expected to be mostly quiet with occasional unsettled episodes due to weak coronal hole wind streams.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 20 stations.
