The Sun produced no flares in the past 24 hours. The probability for a C flare in the next 24 hours is estimated at 25%, mostly from returning NOAA region 2682 which is approaching the East limb. No Earth- directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. Solar wind speed measured by DSCOVR varied between about 340 and 400 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantlty directed away from the Sun and its magnitude ranged between about 2 and 10 nT. Bz was predominantly negative, but there were no extended intervals with Bz below -5 nT. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 0 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels are expected on October 19, 20 and 21.
