Bulletin

Solar activity was very quiet with X-ray flux remaining below B level. Catania sunspot group 86 (NOAA active region 2713) is the only spotted region on the visible disk and it appears stable. Chances for C class flaring remain very low.

Only a small westbound CME was visible in SoHO/LASCO coronagraph images around 17:36UT which will not affect Earth.

Solar proton flux levels were at background values and are expected to remain so.

Solar wind conditions have been nominal with solar wind speed between 300-350 km/s and total magnetic field below 5 nT. The Bz component of the magnetic field was variable. The magnetic field phi angle indicates a negative sector connection. Solar wind conditions are expected to be nominal until at least June 18.

Geomagnetic conditions were quiet (local K Dourbes 1-2 and NOAA Kp 1) and are expected to remain so.

Today's estimated international sunspot number (ISN): 015, based on 18 stations.
