Bulletin

Solar activity was low, no C-class flares in past 24 h. NOAA 2698 rotated over the east limb with simple alpha magnetic field configuration, no significant flares are expected in the coming hours.

Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed.

Solar wind speed is at 330 km/s with interplanetary magnetic field magnitude of 3 nT. Geomagnetic conditions have been quiet. The northern polar coronal hole as a low latitude extension (reaching up to 20 degrees north) that could affect the Earth in 24 h (but it might as well miss it), active conditions can be expected then.

Today's estimated international sunspot number (ISN): 000, based on 11 stations.
