Bulletin

There are currently 8 sunspot groups visible, with NOAA 2104 and NOAA 2107 the most complex and having a small delta. These two regions, together with an active area near the northeast limb, produced most of the C-class flares observed during the last 24 hours. The strongest event was a C3.4-flare peaking at 04:19UT on 30 June. No CMEs with an Earth directed component were observed. Further C-class flares are expected, with a chance on an M-class flare in particular from NOAA 2104. The solar wind speed was around 350 km/s over the last 24 hours. Bz was negative between 22:00 and 02:00UT (max. value around -8 nT), then mainly positive at +5 nT. Geomagnetic conditions were quiet with an usettled period around midnight. A small equatorial coronal hole passed the central meridian early on 27 June and may influence the geomagnetic field on 1 July. Quiet geomagnetic conditions are expected, with locally a brief active episode possible.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 091, sur la base de 20 stations.
