Solar activity has been low in past 24 h, only one C-class flare occurred: C1.7 peaking at 11:37 UT from NOAA AR 2407, that rotated behind the west limb already. More C-class flares are possible. Solar wind speeds have been increasing steadily in past 24 h (from 350 to 450 km/s), marking the expected arrival of the fast speed stream from a coronal hole. A sector boundary crossing was detected also at 15:10 UT on September 2. The interplanetary magnetic field intensity is at 7 nT, only unsettled geomagnetic conditions have been recorded. Active to minor storm periods are possible in the coming 24 h considering the increase in solar wind speed continues.
Today's estimated international sunspot number (ISN): 028, based on 14 stations.
