Bulletin

No C-class flares in past 24 h. The Sun is spotless. 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 5 nT. Geomagnetic conditions have been quiet and are expected to remain so in the coming hours. The fast solar wind associated with a small negative polarity equatorial coronal hole may affect the Earth in 24-48 h, causing isolated active conditions at most.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
