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 new 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 390 and 430 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 1 and 8 nT. There were no long intervals with Bz below -5 nT. A negative polarity coronal hole started crossing the central meridian on March 31. An associated high speed stream may arrive at Earth on April 3.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on April 1 and 2, with a chance for active levels (K Dourbes = 4). Active to minor storm intervals (K Dourbes = 4-5)are possible on April 3, due to the expected arrival of the high speed stream associated with a negative polarity coronal hole.
