公告

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.

今日估計的國際太陽黑子數（ISN）：080，基於11個觀測站。
