Bulletin

The Sun did not produce any flares in the past 24 hours. NOAA AR 2737 showed continued decay. The chance for a C flare in the next 24 hours is estimated at 3%.

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 jumped from about 440 km/s to 510 km/s at 13:22 UT on April 4, while the Interplanetary Magnetic Field (IMF) fell from about 10 to 7 nT. Current solar wind and IMF magnitude values lie around 510 km/s and 5 nT, respectively. The IMF was directed predominantly towards the Sun. Bz was below -5 nT between about 14:10 and 14:50 UT on April 4.

Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 1 and 3) were registered in the past 24 hours. Active intervals (K Dourbes = 4) are possible on April 5 and 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. A return to quiet to unsettled levels (K Dourbes < 4) is expected in the second half of April 7.
