There were no C flares during the past 24 hours. In the next 48 hours, quiet conditions (B flaring) are expected, with a slight chance for a C flare from NOAA AR 2139 and 2135.Over the past 24 hours, solar wind speed as observed by ACE decreased from about 430 to 360 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between 2 and 4 nT. Near 1h UT on August 14, the IMF phi angle changed from negative (towards) to positive (away). Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 3; NOAA Kp between 1 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on August 14, 15 and 16.
