Bulletin

During the past 24 hours, one M flare and four C flares were released by the backside region close to the east limb that produced both M flares on October 14 (probably this region is the return of M-flaring region NOAA AR 2173). The M4.3 flare peaked at 13:03 UT on October 16. In the next 48 hours, M flares are possible, especially from the region near the east limb that has produced the three M flares. Over the last 24 hours the solar wind speeds observed by ACE varied between about 380 and 500 km/s, with current speed values around 435 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 1.5 and 7.5 nT, with current values around 5.5 nT. Geomagnetic conditions during the last 24 hours were quiet to active (K Dourbes between 1 and 4; NOAA Kp between 1 and 3). Quiet geomagnetic levels (K Dourbes < 4) are expected on October 17, 18 and 19.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 044, gebaseerd op 12 stations.
