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 320 and 400 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) changed to towards the Sun at about 4:40 UT on October 14, probably marking the arrival of a weak solar wind stream associated with the negative polarity coronal hole that crossed the central meridian on October 10. The IMF magnitude varied between about 2 and 8 nT. Bz was never below -5 nT for extended periods.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on October 15, 16 and 17.
