Weekly Forecast

During the past 24 hours, solar activity was low. There were four active regions on the visible disk. Region 2786 was large with 800 area and Beta-Gamma type, which produced 1 C-class flares. The solar wind speed increased to about 470 km/s. The geomagnetic field was quiet to unsettled.

Within the next three days, solar activity is expected to be mainly at low levels with a slight chance for M-class flares. The geomagnetic field is expected to be quiet to unsettled.

During last week, solar activity was mainly at low levels with 13 C-class flares produced. There were four sunspot regions on the visible disk, AR2783-2786, in which region 2786 was large with 1000 sunspot unit areas and Beta-Gamma type. The F10.7 index increased from 82 sfu to 106 sfu. Due to the effects of recurrent coronal hole high speed stream, the solar wind speed reached a peak of about 630 km/s during 21-22 Nov, and the geomagnetic field was at minor storm levels for 3 hours and active levels for 18 hours. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 24 Nov.
