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 360 km/s with interplanetary magnetic field magnitude of 5 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 24h (although its associated solar wind stream may pass north of the Earth), active conditions can be expected then (with isolated minor storm periods possible).
Today's estimated international sunspot number (ISN): 007, based on 12 stations.
