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.
