公告

There were two low C flares during the past 24 hours. The brightest one was a C1.1 flare released by NOAA AR 12065, peaking at 9:13 UT on May 24. No new CMEs were observed. In the next 48 hours, the probability for C flares is high (85%) and for M flares around 20%, especially from NOAA AR 12071, 12072, 12073, and 12065. Over the last 24 hours, the solar wind speed as observed by ACE decreased from around 500 km/s to about 450 km/s. Meanwhile the magnitude of the Interplanetary Magnetic Field (IMF) decreased from 12 to 3 nT. Geomagnetic conditions were active (K Dourbes = 4) from 18h until 23h UT on May 23, and there was a minor geomagnetic storm (K Dourbes = 5) from 23h until 1h UT. Quiet geomagnetic levels (K Dourbes < 4) prevailed over the rest of the last 24 hours. NOAA Kp was equal to 4 from 15h until 21h UT on May 23, and equal to 5 from 21h to 0h UT. Quiet geomagnetic levels are expected on May 24 and 25. Quiet geomagnetic conditions with active periods are possible on May 26, due to the expected arrival of a coronal hole high speed stream.
