Bulletin

The Sun produced no C flares in the past 24 hours. C flaring is possible in the next 24 hours (50% probability). A sector boundary crossing from negative to positive was observed in ACE data at 11:23 UT on June 10. From around 20h UT onwards, a high speed stream associated with a positive coronal hole gradually increased solar wind speeds from 360 km/s to a maximum of 600 km/s, with current values near 445 km/s. The magnitude of the Interplanetary Field has been rising since the sector boundary crossing from about 4 to 14 nT, with current values near 6 nT. During the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 2 and 4). Under the influence of the positive coronal hole high speed stream, active geomagnetic conditions are possible on June 11 and 12, with a chance for minor storm intervals (K Dourbes = 5). Quiet to unsettled levels are expected on June 13.

Today's estimated international sunspot number (ISN): 044, based on 12 stations.
