Bulletin

Active Region NOAA 2765 produced no B or brighter flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 5%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR varied between about 420 and 500 km/s in the past 24 hours, with current values around 440 km/s. The Interplanetary Magnetic Field (IMF) was oriented away from the Sun, and its magnitude varied between about 2 and 5 nT. Bz was never below -5 nT. Nominal to slightly enhanced solar wind conditions are expected in the next 24 hours.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on June 11, 12 and 13.

Today's estimated international sunspot number (ISN): 010, based on 09 stations.
