Bulletin

The Sun produced no C flares in the past 24 hours. The chance for a C flare to occur in the next 24 hours is estimated at 5%. 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 265 and 310 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 1 and 7 nT. Quiet to unsettled geomagnetic conditions (K Dourbes between 0 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on June 11, 12 and 13.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
