Bulletin

No C flares were registered during the past 24 hours. In the next 48 hours, eruptive conditions (C flaring) are possible, especially from beta-gamma regions NOAA AR 2144 and 2139. Over the past 24 hours, solar wind speed as observed by ACE was stable around 280 km/s until it jumped to a plateau of about 300 km/s around 23h UT on August 16. Meanwhile, the magnitude of the Interplanetary Magnetic Field (IMF) increased from about 2 to 8 nT. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 2; NOAA Kp between 0 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on August 17, 18 and 19. The expected arrival of the halo CME of August 15 at the end of August 19 may induce active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 080, based on 11 stations.
