The Sun produced a few B flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 40%, mainly from beta region NOAA AR 2712.

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.

Solar wind speed near Earth as registered by ACE and DSCOVR varied between about 320 and 405 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) fluctuated in its direction away from and towards the Sun, while its magnitude varied between about 0 and 6 nT. Bz was never below -5 nT. A high speed stream associated with a negative polarity equatorial coronal hole is expected to arrive near Earth late on May 31 or on June 1.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on May 31, with a chance for active to minor storm intervals (K Dourbes between 4 and 5) late on May 31 due to the expected arrival of the solar wind stream associated with the equatorial coronal hole. Active to minor storm levels are possible on June 1 and 2.
