Bulletin

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. The small bright region that rotated into view yesterday is only a plage without sunspots. 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 400 km/s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions were quiet to unsettled. Late on October 29 or on October 30, the arrival of the CME from October 25 and a high speed stream from a negative polarity coronal hole may cause an increase in geomagnetic conditions (most likely not greater than K = 4).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 19 stations.
