Bulletin

Only one C-class flare was observed during the period: a C2.5 originating south of NOAA 2449's trailing portion at 23:21UT. This active region is currently the most complex group on the solar disk. A filament has developed between NOAA 2448 and 2451, and also trailing NOAA 2448 and NOAA 2443. The other regions were stable and quiet. No earth-directed coronal mass ejections have been observed.

C-class flares are expected.

Quiet to active geomagnetic conditions were recorded in the aftermath of the passage of the coronal mass ejection (CME). Solar wind speed declined slowly from its initial 550 km/s to its current values near 460 km/s. Bz was near zero until about 19:00UT and after 07:00UT, while in between it was fairly positive with a maximum around +11 nT during the 00-02UT interval. It dipped again to -9 nT between 10:00 and 11:00UT.

Further quiet to active geomagnetic conditions are expected, until the arrival of the co-rotating interaction region and high speed stream associated with the northern coronal hole later today or tomorrow, which could produce minor storming episodes.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 076, gebaseerd op 16 stations.
