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 5 nT. Geomagnetic conditions have been quiet and are expected to remain so for the next 48 h. The fast solar wind associated with a small negative polarity equatorial coronal hole is expected to arrive on 3 October (late) or 4 October.
