Bulletin
Beta region NOAA AR 2661 (Catania region 29) produced a C1.4 flare peaking at 3:30 UT on June 7. Catania region 30, near 90W20N, released a C1.3 flare at 10:20 UT. The chance for a C flare to occur in the next 24 hours is estimated at 55%. 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 325 and 370 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 2 and 8 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on June 7, 8 and 9.
