No C-class flares in past 24 h. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 400 km/s with interplanetary magnetic fields of 3 nT. Geomagnetic conditions have been quiet and are expected to remain so for the next 48 h. The fast solar wind associated with a negative polarity equatorial coronal hole may affect the Earth after that.

Today's estimated international sunspot number (ISN): 000, based on 18 stations.
