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 maintained at about 600 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 be quiet to unsettled.

During last week, solar activity was very low. There were no active regions on the visible disk, with no C class and above flares produced. The F10.7 index ranged from 67 sfu to 70 sfu. Due to the effects of the coronal hole high speed stream, the solar wind speed reached a peak of about 630 km/s on 4-6 Nov, and the geomagnetic field was at moderate storm levels for 3 hours, minor storm levels for 12 hours and active levels for 9 hours. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 6-8 Nov.

Within the next week, solar activity is expected to be very low. Due to recurrent coronal hole high speed streams, the geomagnetic field will be minor storm levels on 9-10 Nov and 14-15 Nov. It will be mainly quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit will reach minor storm levels on 11-13 Nov.
