Weekly Forecast

During the past 24 hours, solar activity was very low. There was no active region on the visible disk, without C-class and above flares produced. The solar wind speed decreased to about 430 km/s. The geomagnetic field was quiet.The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm level.

Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to be mainly quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain minor storm level on 13 Dec.

During last week, solar activity was very low. There was one active region 2729 on the visible disk, with no C class and above flares produced. The F10.7 index ranged from 68 sfu to 71 sfu. Due to recurrent coronal hole high speed stream, the solar wind speed increased to about 470 km/s on 2 Dec, and the geomagnetic field reached active levels for 3 hours. It was quiet to unsettled during other periods.

Within the next week, solar activity is expected to be very low. Due to recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active levels on 7-9 Dec. It will be mainly quiet to unsettled for the rest of time.
