Bulletin

A new (solar cycle 25) active region emerged near the southeast limb (and a very small one in the northern hemisphere), no NOAA number yet, the Sun is not spotless anymore. Solar activity has been very low, no flares in the past 24 h. Low solar activity expected for the next 48 h, but the development of the new ARs may increase slightly the activity.

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

The solar wind speed is at 340 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions have been quiet. The fast solar wind emanating from a small equatorial negative polarity coronal hole might affect Earth on December 24-25, but its effect will be weak (mostly unsettled conditions expected, with possible isolated active periods).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 09 stations.
