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 345 km/s with interplanetary magnetic field magnitude of 6 nT. Geomagnetic conditions have been quiet to unsettled and are expected to remain so. Isolated active periods are possible in the next 48 h, due to the possible arrival of moderately fast solar wind streams associated with diffuse coronal holes.
Today's estimated international sunspot number (ISN): 000, based on 12 stations.
