The Sun did not produce any flares in the past 24 hours. While NOAA AR 2737 decayed into a plage, the coronal loops from old NOAA region AR 2736 have appeared at the East limb. The chance for a C flare in the next 24 hours is estimated at 15%, especially from the returning region at the East limb.

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 465 and 535 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 7 nT. Bz was never below -5 nT.

Quiet to unsettled geomagnetic conditions (K Dourbes between 2 and 3; NOAA Kp between 2 and 3) were registered in the past 24 hours. Active intervals (K Dourbes = 4) are possible on April 6 and the first half of April 7, with a slight chance for minor storm levels (K Dourbes = 5) due to the influence from isolated negative polarity coronal holes. Quiet to unsettled levels (K Dourbes < 4) are expected in the second half of April 7 and on April 8.
