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 420 km/s. The geomagnetic field was quiet to unsettled.

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. The solar wind speed increased to about 500 km/s on 10 Oct. The geomagnetic field was active levels for 9 hours on 9-10 Oct. The geomagentic field was quiet to unsettled during other periods. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 4 Oct.

Within the next week, solar activity is expected to be very low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active levels on 14-15 Oct. It will be quiet to unsettled during other periods.
