Bulletin

Solar activity was restricted to only a few B-class flares. The strongest was a B7.9 flare (peaking at 22h35 UT) as maximum, which was associated with a prominence eruption and dimming at the East limb. No CME signature has not been observed yet, though there is a data gap in SOHO/LASCO imagery. In case of a CME associated with the event, no Earth- directed component is expected. The probability for C-class flares or above is low (20%).

Solar wind observations are nominal with a magnetic field magnitude below 5 nT and a solar wind speed decreasing from 450 to currently 380 km/s. Geomagnetic conditions are quiet (K<3) and are expected to remain so. A negative polarity equatorial coronal hole (CH) is currently crossing the central meridian; the high speed stream emanating from that CH is expected to disturb the solar wind from June 5.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 016, sur la base de 14 stations.
