Bulletin

Solar activity has been low, NOAA AR 2371 still has potential for important flares although it is rotating over the west limb, it produced a C1.1 flare peaking at 06:12 UT. Recurrent active regions are rotating into view now and may increase solar activity in the coming hours. Proton levels are elevated but below the 10 pfu threshold. The CME from June 25 was less geoeffective than expected, only unsettled conditions were seen at planetary levels (and active locally at Dourbes) yesterday. Quiet to unsettled geomagnetic conditions are expected for the next 48h.

Today's estimated international sunspot number (ISN): 022, based on 15 stations.
