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 3 nT. Geomagnetic conditions have been quiet and are expected to remain so for the next 48 h. The fast solar wind associated with a negative polarity equatorial coronal hole may affect the Earth after that.
