Solar activity was low, no C-class flares in past 24 h. The situation is not expected to change, as there are no active regions on disk.
Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed.
Solar wind speed is at 340 km/s with interplanetary magnetic field magnitude of 3 nT. Geomagnetic conditions have been quiet to unsettled and are expected to remain so. Isolated active periods remain possible in the next 24 h, due to the probable arrival of moderately fast solar wind streams associated with a negative polarity diffuse equatorial coronal hole.
