Solar activity was low, no C-class flares in past 24 h. The new compact region that appeared on the northeast limb has not been active. C-class flares are possible but unlikely.
Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed.
Solar wind speed is at 390 km/s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions have been quiet. There is a small positive coronal hole located at 30 degrees northern latitude which may affect the Earth within 48h, active conditions can be expected then (with isolated minor storm periods possible).
