The Sun produced several B flares in the past 24 hours. NOAA AR 2712 has evolved to beta-gamma, and an active region is appearing near the East limb. The chance for a C flare in the next 24 hours is estimated at 60%, mainly from both regions mentioned above.

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.

Around 14:15 UT on May 31, the Interplanetary Magnetic Field (IMF) as observed by DSCOVR changed from a positive (away from the Sun) to a negative (towards the Sun) sector, while its magnitude increased from about 4 nT to a maximum value of around 17 nT. Current IMF magnitude values are near 8 nT. Bz fluctuated between positive and negative values, with a minimum value of about -12 nT. Since about 16:00 UT, solar wind speed started rising gradually from about 375 km/s to current values near 620 km/s. This marks the expected arrival of the Corotating Interaction Region (CIR) and high speed stream associated with a negative polarity equatorial coronal hole.

Quiet to active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between 2 and 4) were registered in the past 24 hours. Active to minor storm levels are possible on June 1, 2 and 3 due to the effects of the high speed stream associated with the equatorial coronal hole, with a chance for moderate storm intervals (K Dourbes = 6).
