Bulletin

One active region visible on the solar disc, NOAA 2723 with beta magnetic field configuration. No C-class flares in past 24 h. Solar activity is expected to remain at 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 410 km/s with interplanetary magnetic fields of 3 nT. Geomagnetic conditions have been quiet. The fast solar wind associated with a small negative polarity equatorial coronal hole is expected to arrive later today or tomorrow, causing up to active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 012, based on 19 stations.
