The Sun has produced a few low B flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 30%, mainly from beta-gamma 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.

The solar wind speed as observed by DSCOVR increased from about 620 km/s to maximum values near 750 km/s (with several outliers near 800 km/s), and is now near 640 km/s. The Interplanetary Magnetic Field (IMF) was directed towards the Sun, and its magnitude decreased from about 9 nT to about 3 nT. There were no extended periods with Bz smaller than -5 nT. Enhanced solar wind conditions are expected on June 2 and 3.

Quiet to minor storm conditions (K Dourbes between 1 and 5; NOAA Kp between 3 and 5) were registered in the past 24 hours, with just one K Dourbes = 5 interval at 12h UT on June 1. Active geomagnetic levels (K Dourbes = 4) are possible on June 2 and 3 due to the ongoing effects of the high speed stream associated with an equatorial coronal hole, with a chance for minor storm intervals (K Dourbes = 5). On June 4, a return to quiet to unsettled geomagnetic levels is expected (K Dourbes < 4), with a chance for active intervals (K Dourbes = 4).
