Solar activity has been quiet during the past 24 hours, featuring no C flares. There is a chance for C flares within the next 48 hours. The solar wind speed decreased from 420 to 380 km/s in the past 24 hours. In the same period, the Interplanetary Magnetic Field rose from 5 to 9 nT. The geomagnetic activity was at quiet levels (K Dourbes between 0 and 2; NOAA Kp between 1 and 3) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for September 3 and 4, with a chance for active periods from the second half of September 4 onwards, due to the effects of a Coronal Hole high speed stream.
