Bülletään

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.
