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 was steady around 300 km/s, with Bz varying between -3 and +1 nT (DSCOVR). The direction of the interplanetary magnetic field (phi angle) was mostly in a sunward orientation (negative sector), being in a positive sector from 18:45UT till about 21UT.

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be mostly quiet with an occasional unsettled episode possible.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 26 stations.
