NOAA AR 2733 produced three C-class flares in the past 24 hours, the strongest one was a C5.2 flare peaking at 06:11 UT. This AR is rotating over the west limb and no other AR is visible, low solar activity is thus expected, although isolated C-class flares remain possible.
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 280 km/s with interplanetary magnetic fields of 2 nT. Geomagnetic conditions have been quiet. The fast solar wind associated with a negative polarity equatorial coronal hole is expected to arrive to the Earth within 24 hours, causing disturbed conditions (most likely up to K = 5).
