During the past 24 hours, solar activity was very low without C-class and above flare produced. There was one sunspot region on the visible disk. The solar wind speed maintained at about 300 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 quiet to unsettled on 17 Jan, and reach isolated active levels on 18-19 Jan with the effect of a recurrent coronal hole high speed stream.

During last week, solar activity was very low to low with 5 C-class flares produced. There were 5 sunspot regions on the visible disk. The F10.7 index decreased from 100 sfu to 82 sfu. AR2790 produced a C7.4 flare associated with a halo CME on 7 Dec and the geomagnetic field reached active levels for 3 hours on 10 Dec. It was quiet to unsettled during other periods.
Within next week, solar activity is expected to be very low. The geomagnetic field is expected to be quiet to unsettled.
