Bulletin

Active Region NOAA 2765 produced a few B flares in the past 24 hours. The chance for a C flare in the next 24 hours, especially from NOAA 2765, is estimated at 30%.

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 increased from about 340 to 500 km/s in the past 24 hours, with current values around 475 km/s. This is probably related to patchy extensions of the northern coronal hole. The Interplanetary Magnetic Field (IMF) was oriented predominantly away from the Sun, and its magnitude varied between about 0 and 13 nT, with current values of around 3 nT. Bz was below -5 nT between 17:30 and 19:15 UT on June 7. 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 4) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on June 8, 9 and 10, with a chance for isolated active intervals (K Dourbes = 4).

Today's estimated international sunspot number (ISN): 016, based on 20 stations.
