The Sun produced no C flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 25%.

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. The greater than 2 MeV electron flux was at nominal levels in the past 24 hours, and may rise to moderate levels in the next 24 hours. The greater than 2 MeV electron fluence was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

The solar wind speed as registered by DSCOVR varied between about 550 and 660 km/s in the past 24 hours. The Interplanetary Magnetic Field near Earth (IMF) was oriented towards the Sun and its magnitude varied between about 1 and 8 nT. There were no extended intervals with Bz below -5 nT. Enhanced solar wind conditions are expected in the next 24 hours, followed by a gradual return towards nominal levels.

Quiet to unsettled geomagnetic conditions (K-BEL between 2 and 3; NOAA Kp between 2 and 4) were registered in the past 24 hours. Active intervals (K-BEL = 4) are possible on November 17 and 18, with a chance for minor storm intervals (K-BEL = 5). Quiet to unsettled geomagnetic levels are expected on November 19, with a chance for active intervals.
