Bulletin

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. Low solar activity expected.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 390 km/s with interplanetary magnetic field magnitude of 14 nT. Geomagnetic conditions have been quiet to unsettled. The interplanetary magnetic field switched polarity (from positive to negative) around 20:00 UT on October 29, together with a steady increase in its magnitude, marking the upcoming arrival of the high speed stream from a negative polarity coronal hole. If the CME from October 25 arrived to the Earth (it may have missed it), its signatures are too weak (yet) to clearly identify it in the data.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 12 stations.
