Bulletin

There are four active regions visible on the solar disk. NOAA active region 2550 and new region 2551 were responsible for some minor flaring, including a single C1.0 flare (from NOAA 2550, peaking at 13:24). NOAA 2548 is rounding the west limb. An isolated C-class flare may occur, but no major flares are expected. No Earth-directed coronal mass ejections (CMEs) were observed.

ACE observations indicate the weakening influence of the high speed stream (HSS). The solar wind speed has decreased to about 450 km/s, the magnitude of the magnetic field reached maximally 6 nT, with a fluctuating Bz. Geomagnetic conditions were quiet to unsettled (maximum K=3), both at local (Dourbes) and global levels (Potzdam, NOAA), which is expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 035, gebaseerd op 14 stations.
