No C-class flares in the past 24 hours, NOAA AR 2733 rotated over the west limb. There are no active regions visible. Eight B-class flares were observed (still from NOAA AR 2733), the strongest one was a B9.7 flare peaking at 17:05 UT on 30 January. Low solar activity is expected.

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 350 km/s with interplanetary magnetic fields of 14 nT. Geomagnetic conditions have been quiet. Solar wind density, speed, temperature and magnetic field have been increasing since last night, together with a sector boundary crossing (from positive to negative magnetic field polarity), marking the arrival of the fast solar wind associated with a negative polarity equatorial coronal hole. Disturbed geomagnetic conditions (most likely up to K=5) are expected for the next 48 hours.
