Bulletin

Solar activity was low. NOAA 2699 has developed from alpha to beta magnetic field configuration and produced several B-class flares. 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 was between 400-450 km/s with interplanetary magnetic field magnitude ranged from 4 to 7 nT. Geomagnetic conditions have been mostly quiet.

A low latitude extension of the northern polar coronal hole could still affect the Earth in the next 24 hrs, unsettled geomagnetic conditions can be expected then.

Today's estimated international sunspot number (ISN): 017, based on 12 stations.
