The Sun produced no flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 10%.

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 solar wind speed as registered by DSCOVR jumped from about 380 to 430 km/s around 1:25 UT on May 18, accompanied by a drop in temperature from about 150000 to 20000 K and a drop in density from about 9 to 2 particles per cc. This could correspond to the arrival of the May 13 CME. The solar wind speed varied between about 360 and 455 km/s in the past 24 hours, with current values around 410 km/s. The Interplanetary Magnetic Field was predominantly oriented away from the Sun and its magnitude varied between about 3 and 8 nT. Bz was never below -5 nT. Enhanced solar wind conditions are possible on May 18 and 19.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 0 and 2) were registered in the past 24 hours. Active intervals (K Dourbes = 4) are possible on May 18 and 19, with a slight chance for minor storm intervals (K Dourbes = 5). A return to quiet to unsettled geomagnetic levels is expected on May 20.
