The Sun did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 5%. 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 decreased from about 530 to about 475 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed away from the Sun and its magnitude ranged between about 1 and 4 nT. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels are expected on October 17 and 18, with a chance for active intervals (K Dourbes = 4). Active conditions are possible on October 19, with a chance for minor storm intervals (K Dourbes = 5), under the influence of another high speed stream associated with a negative equatorial coronal hole.
