One C flare as well as several high B flares were registered during the past 24 hours. The C1.1 flare was released by NOAA AR 2139 and peaked at 12:00 UT on August 15. In the next 48 hours, eruptive conditions (C flaring) are likely, especially from NOAA AR 2141 and 2139. Over the past 24 hours, solar wind speed as observed by ACE varied between about 325 and 360 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between 1.5 and 4.5 nT. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 2; NOAA Kp between 1 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on August 15, 16 and 17.
