Solar activity has been very low, no C-class flares in past 24 h. Two simple (alpha magnetic field configuration) active regions visible on the disk, C-class flares are possible.
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.
Geomagnetic conditions have reached K=4 overnight due to the effect of a high speed stream. Solar wind speed is now at 570 km/s with interplanetary magnetic fields of 3 nT. There is a small equatorial coronal hole which may affect the Earth within 48 h. Geomagnetic conditions may reach K = 4 again.
