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 reached a peak of about 410 km/s. The geomagnetic field was quiet to unsettled.

During last week, solar activity was low. There was one active region 2732 on the visible disk, with no M class and above flares produced. The F10.7 index ranged from 70 sfu to 72 sfu. Due to recurrent coronal hole high speed stream, the solar wind speed increased to about 520 km/s on 5 Jan, and the geomagnetic field reached minor storm levels for 3 hours and active levels for 3 hours. It was quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 7 Jan.
