Solar activity was low with a couple of low C flares. All those flares were from NOAA active region 3030 in the northeast. The most significant one was a long duration C1.8 flare peaking at around 8:38UT. NOAA active region 3029 has decayed into plage and footpoint spreading and decay was observed in the new region NOAA 3031. The larger bipolar region NOAA 3030 remains the most significant region on disc. Flaring at C level is expected with still a chance for an isolated M flare.

No new Earth directed CMEs have been recorded in coronagraph data.

The greater than 10 MeV proton flux was at background levels and is expected to remain so. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold. The 24h electron fluence was at normal levels and is expected to be at low to normal levels.

An equatorial positive polarity coronal hole is transiting the central meridian. It is expected to influence Solar wind near Earth from June 15 onwards.

Slow solar wind conditions were observed. Though after 8UT solar wind speed has seen an increase to around 450 km/s. The interplanetary magnetic field also became enhanced with a magnitude now reaching 15 nT. The north-south component was variable with Bz peaking down to -11nT. The phi angle now indicates connection with a positive sector (magnetic field away from the Sun). Essentially slow solar wind conditions are expected over the next days. An increase in solar wind conditions is expected by 15 June under the influence of the high speed stream from a positive polarity coronal hole.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-2 and local K Belgium 0-3). Quiet to unsettled geomagnetic conditions are expected over the next days.
