Bulletin

NOAA AR 2661 produced some C flares in the past 24 hours. The chance for a C flare to occur in the next 24 hours is estimated at 33%. No Earth directed CMEs have been observed in available coronagraph images. Proton flux levels are at background values and are expected to remain so. Solar wind speed measured by DSCOVR varied between about 290 and 350 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 0.5 and 5 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on June 8, 9 and 10.

Today's estimated international sunspot number (ISN): 016, based on 16 stations.
