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 15%. A filament eruption near 10E45S – 10W35S was observed in SDO/AIA 30.4 nm imagery around 18h UT on November 17.

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 decreased from about 580 to 545 km/s in the past 24 hours. The Interplanetary Magnetic Field near Earth (IMF) was predominantly oriented towards the Sun and its magnitude varied between about 0 and 6 nT. Bz was never below -5 nT. A gradual return towards nominal levels is expected in the next 24 hours.

Quiet to unsettled geomagnetic conditions (K-BEL between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K-BEL < 4) are expected on November 18, 19 and 20, with a chance for active intervals (K-BEL = 4) on November 18.
