公告

There were five C flares and an M flare during the past 24 hours, all released by NOAA AR 12065. The long duration M1.3 flare peaked at 18:35 UT on May 24. No Earth-directed CMEs were observed. STEREO COR2 B imagery registered a CME at 23:09 UT on May 24, but this CME was probably associated to a backside event. In the next 48 hours, the probability for C flares is very high (95%) and for M flares around 60%, especially from NOAA AR 12065. Over the last 24 hours, the solar wind speed as observed by ACE decreased from around 450 km/s to about 430 km/s. Meanwhile the magnitude of the Interplanetary Magnetic Field (IMF) varied between 2 and 4 nT. Over the last 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 3; NOAA Kp between 1 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on May 25 and 27. Quiet geomagnetic conditions with active (K Dourbes = 4) periods are possible on May 26, due to the expected arrival of a coronal hole high speed stream.
