There are currently 6 sunspot regions visible on the solar disk. Six C1 flares were produced: 3 by NOAA 2253, 2 by NOAA 2250 and 1 by NOAA 2251. NOAA 2253 is currently the most complex sunspot region, showing some mixed polarities. No significant or earth-directed CMEs were detected. Further C-class flaring is likely, in particular from NOAA 2253. Solar wind speed continued its gradual decline from its initial value of about 670 km/s to its current 500 km/s. Bz varied between mostly -4 and +3 nT. The geomagnetic field was mostly unsettled during the first half of the period, then turned to quiet conditions. Quiet to unsettled conditions are expected, though an active episode cannot be excluded.
Today's estimated international sunspot number (ISN): 071, based on 16 stations.
