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.

Geomagnetic conditions have been quiet. The solar wind speed is at 350 km/s with interplanetary magnetic fields of 2 nT. The fast solar wind associated with a small positive polarity equatorial CH may influence the Earth within 24 h, resulting in isolated active episodes.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
