Bulletin

The Sun is spotless and did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 1%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by ACE varied between about 310 and 360 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed away from the Sun before 3h UT on October 14, and predominantly towards the Sun afterwards, and its magnitude varied between about 1 and 6 nT. Bz was never below -5 nT. Weak enhancements in the solar wind are possible on October 14 and 15 due to the influence of a negative polarity coronal hole that crossed the central meridian on October 10.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on October 14, 15 and 16.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 23 stations.
