Bulletin

Solar activity remained at very low levels. The visible solar disk was spotless. No earth-directed coronal mass ejections (CMEs) were observed during the period. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Solar wind speed varied mostly between 330 and 370 km/s (DSCOVR). Bz ranged between -4 and +4 nT. The direction of the interplanetary magnetic field (phi angle) was predominately towards the Sun (negative sector). Quiet geomagnetic conditions were observed.

Mostly quiet geomagnetic conditions are expected until the arrival of the co-rotating interaction region and the high speed wind stream associated with the positive polarity equatorial coronal hole. This arrival is expected for later today or on 4 November. Geomagnetic conditions may then reach minor storm levels, a moderate storming episode not excluded.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 18 stations.
