Weekly Forecast

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

During last week, solar activity was very low. There was no active region on the visible disk, without C class and above flare produced. The F10.7 index ranged from 67 sfu to 68 sfu. Due to the effect of a coronal hole high speed stream, the solar wind speed reached a peak of about 670 km/s on 9-10 Aug. The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit maintained at minor storm levels on 9-15 Aug.
