Bulletin

Solar activity was at very low levels. No coronal mass ejections (CME) were observed over the last 24 hours. Analysis of STEREO-A coronagraphic imagery indicates that the slow and narrow CME from the 7 June filament eruption was mainly directed south of the ecliptic, making a geo-effective impact rather unlikely. The greater than 10 MeV proton flux was at nominal values. An extension from the positive polarity northern polar coronal hole (CH) transited the central meridian on 8 June. This extension is better defined than during its previous rotation.

Solar wind speed declined from about 410 km/s to its current values near 340 km/s. Bz varied between -4 and +3 nT. The direction of the interplanetary magnetic field (phi angle) was mostly directed towards the Sun. Quiet geomagnetic conditions were observed, with unsettled levels reached at Dourbes during the 15-18UT and 06-09UT intervals.

Quiet to unsettled geomagnetic conditions are expected to continue until the arrival of the CH wind stream late on 11 or on 12 June. Active conditions are then possible.
