Bulletin

Solar activity has been very low with X-ray flux remaining below B level. As the only region on disk (the bipolar Catania group 86; NOAA region 2713) is stable and inactive, chances for C flaring remain very low.

No Earth directed CMEs have been recorded in coronagraph images.

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

A recurrent positive polarity coronal hole at low latitude in the Northern hemisphere is about to cross the central meridian. Its high speed stream may possibly influence the solar wind conditions around Earth from June 18 onwards.

Solar wind conditions were nominal with solar wind mainly around 300 km/s and with an increasing trend towards 350 km/s currently. Total magnetic field was between 2-8nT with Bz seeing a downward peak close to -6nT. Solar wind speed may see some further increase but overall conditions should remain near nominal.

Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 1-2) with an isolated unsettled period locally. Geomagnetic conditions are expected to remain quiet with initially still an isolated unsettled period possible.

Today's estimated international sunspot number (ISN): 016, based on 13 stations.
