Bulletin

NOAA 2723 rotated over the west limb, there are no active regions visible on the solar disk. 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 380 km/s with interplanetary magnetic fields of 3 nT. Geomagnetic conditions have been quiet to unsettled. The fast solar wind associated with a positive polarity coronal hole will arrive to the Earth on October 7-8, causing disturbed geomagnetic conditions (with K probably arriving up to 6).

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