The Sun did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours, especially from beta region NOAA AR 2737, is estimated at 5%.

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 DSCOVR varied between about 340 and 450 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed predominantly towards the Sun and its magnitude varied between about 1 and 8 nT. There were no long periods with Bz below -5 nT.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 4) were registered in the past 24 hours. Active to minor storm intervals (K Dourbes = 4-5) are possible on April 3 and 4, due to the expected arrival of the high speed stream associated with a negative polarity coronal hole. Active intervals (K Dourbes = 4) are possible on April 5.
