Bulletin

Solar flaring was low. NOAA active region 2552, as it was departing over the West limb, produced the two C flares of the period. The strongest was a C3.0 flare peaking at 5:52UT. Region 2554 (Catania group 90) became slightly more active with a B9.3 flare as biggest achievement. Region 2554 (Catania group 90) is the only complex region (Dao, beta) on disk and could be a potential source for C flaring, although with probability below 50%. No Earth directed CME's have been recorded in coronagraph data. A large positive polarity coronal hole in the Northern hemisphere, as well as a smaller equatorial coronal hole started crossing the central meridian over the past 24 hours. These may become geo-effective from late June 15 onwards. Solar wind speed has increased over the past 24 hours from around 420 km/s to a maximum of close to 600 km/s and is currently at around 530 km/s. Total magnetic field was decreasing from around 12 nT to around 6nT with Bz mostly variable with peaks down to -10nT occurring before the increase in speed. The magnetic field phi angle was in the positive sector. The solar wind conditions are expected to further recover towards nominal although later, around late June 15 to 16, a new coronal hole high speed stream influence is expected. Geomagnetic conditions reached some isolated periods of active conditions (local K Dourbes 4 around 18UT and NOAA Kp 4 at 3UT) but were otherwise quiet to unsettled. Further quiet to unsettled conditions are expected while solar wind speeds recovers towards nominal. From late June 15 onwards geomagnetic conditions may increase.
