Three ARs on the visible disk, all with simple magnetic field configuration. No C-class flares in past 24 h, they remain possible in the next 24 h.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.
The Earth is still inside a high speed solar wind stream, geomagnetic conditions reached minor storm levels locally (K = 5) and major storm at planetary levels (Kp = 6). The solar wind speed increased to reach 750 km/s currently with interplanetary magnetic fields of 7 nT. Disturbed geomagnetic conditions are expected to prevail for the next 24 h.
