Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was no sunspot region on the visible disk. The solar wind speed maintained at about 410 km/s. The geomagnetic field was quiet to unsettled.

During last week, solar activity was very low. There was no sunspot region on the visible disk, without C-class and above flares produced. The F10.7 index ranged from 70 sfu to 72 sfu. Due to the continuous effect of the coronal hole high speed stream, the solar wind speed reached a peak of about 650 km/s and the geomagnetic field was at active levels for 3 hours on 31 Jan. It was quiet to unsetteld during other periods.The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 8-10 Feb.
