Bulletin

There are currently 5 sunspot regions visible. Three C-class flares were recorded over the last 24 hours. Near the time of its disappearance from the solar surface, active region NOAA 2076 produced a C1-flare peaking at 15:56UT. The strongest event of the period was a C2-flare in NOAA 2079 peaking at 01:37UT. The associated CME was directed away from Earth. NOAA 2077 produced a C1-flare peaking at 11:53UT. Further C-class flaring is expected, in particular from sunspot regions NOAA 2077 and NOAA 2079. Solar wind speed declined from about 350 to 300 km/s, Bz being mostly positive with maximum excursions to +8 nT. The geomagnetic field was quiet. A small coronal hole that passed the central meridian on 29 May can influence the geomagnetic field as of 2 June. Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 045, sur la base de 17 stations.
