Returning region NOAA 2736 at the East limb produced several B flares. The brightest flare was a B9 flare peaking at 11:00 UT on April 7. The chance for a C flare in the next 24 hours is estimated at 50%, especially from returning region 2736.

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 385 and 530 km/s in the past 24 hours, with current values around 400 km/s. The Interplanetary Magnetic Field (IMF) was directed predominantly towards the Sun and its magnitude varied between about 2 and 4 nT, with current values around 3 nT. Bz was never below -5 nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected in the second half of April 7, and on April 8 and 9.
