Bulletin

NOAA 2585 developed a small delta in its main trailing spot and produced a B6.6 flare peaking at 10:40UT, the strongest flare of the period. NOAA 2588 and a new region near the west limb (Catania 25) produced a minor B-class event each. The 40-degrees long filament in the northwest quadrant remained quiet. No earth-directed coronal mass ejections (CME) were observed.

C-class flares are possible, with a chance on an isolated M-class event.

Solar wind speed continued its gradual decline from about 520 km/s to its current value near 470 km/s. Bz fluctuated between -5 and +4 nT. The interplanetary magnetic field (IMF) was mostly directed away from the Sun (positive). Quiet to unsettled geomagnetic conditions were observed, with an isolated active episode during the 18-21UT interval.

Quiet to unsettled geomagnetic conditions are expected, with a chance on an active episode in response to the waning effects of the coronal hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 061, gebaseerd op 27 stations.
