Alpha region NOAA 2741 produced a C2.0 flare peaking at 19:24 UT on May 15. The chance for a C flare in the next 24 hours, especially from region 2741, is estimated at 40%.

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 varied between about 400 and 460 km/s in the past 24 hours, with current values around 420 km/s. The Interplanetary Magnetic Field was directed predominantly away from the Sun, and its magnitude varied between about 2 and 10 nT, with current values around 6 nT. Bz was never below -5 nT for extended periods. Enhanced solar wind conditions are expected in the next days, with the expected arrival of the May 11, 12 and 13 CMEs.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Active to moderate storm intervals (K Dourbes = 4-6) are possible on May 16 and 17, due to the expected arrival of the May 11, 12 and 13 CMEs. A return to quiet to unsettled geomagnetic levels is expected on May 18.
