Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was 1 sunspot region on the visible disk. The solar wind speed maintained at about 350 km/s. The geomagnetic field was at quiet levels.

During last week, solar activity was very low. There was one sunspot region on the visible disk (AR2813), Without C-class and above flares produced. The F10.7 index fluctuated between 70 sfu to 76 sfu. Due to the effect of co-rotating interaction region, the solar wind speed reached a peak of about 520 km/s and the geomagnetic field reached minor storm levels for 3 hours and active levels for 6 hours on 7 Apr.

Within next week, solar activity is expected to be mainly very low. Due to the effect of recurrent coronal hole high speed streams, the geomagnetic field is expected to reach isolated active levels on 10 Apr. It will be quiet to unsettled during other periods.
