During the past 24 hours, solar activity was very low. There was one small active region 2729 on the visible disk, without C-class and above flares produced. The solar wind maintained at about 400 km/s. The geomagnetic field was quiet.
Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to be mainly quiet to unsettled and reach isolated active levels due to the effect of a recurrent coronal hole high speed stream.

During the past 24 hours, solar activity was very low. There was one small active region 2729 on the visible disk, without C-class and above flares produced. Due to the effect of a recurrent coronal hole high speed stream, the solar wind speed increased to about 490 km/s. The geomagnetic field was quiet to unsettled.
Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to reach isolated active levels on 8-9 Dec due to the effect of the recurrent coronal hole high speed stream and be mainly quiet to unsettled on the rest of time.
