Bulletin

Several C-class and one M-class flares erupted since our last bulletin. Activity mostly originated from NOAA active regions 2227 (Catania 27), 2237 and a new region located at the East limb (S05). The impulsive M1.5 flare peaking at 5:20 UT, originated from the new yet unnumbered region near the East limb. More flares at the C-level is expected, with a probability of 40% for an isolated M-flare. No Earth-directed CMEs were observed. Solar wind speed varied between 500 and 700 km/s and the magnitude of the interplanetary magnetic field was maximally around 10 nT, decreasing to 7 nT with a fluctuating Bz component. The geomagnetic index reached K=4 at Dourbes. Geomagnetic activity is expected to reach unsettled to active conditions, related to effects of the coronal hole high speed stream. Isolated time slots of minor storm conditions are also possible.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 099, gebaseerd op 05 stations.
