Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was two sunspot regions on the visible disk. The solar wind speed reached a peak of 580 km/s. The geomagnetic field was at active levels for 6 hours and quiet to unsettled levels for rest of the time.

Within the next three days, solar activity is expected to be very low. Due to the effect of the recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active levels on 7 Mar. It will be mainly at quiet to unsettled levels on 8-9 Mar.

During last week, solar activity was very low to low. There were four sunspot regions on the visible disk. Three C-class flares were produced. The F10.7 index fluctuated between 71sfu to 81sfu. Due to the effect of the coronal mass ejection produced on 26 Feb, the solar wind speed increased to about 530 km/s on 26 Feb. The geomagnetic field reached mediun storm levels for three hours, minor storm levels for three hours and active levels for three hours,respectively. Due to the effect of the current coronal hole high speed stream, the solar wind speed increased to about 660 km/s on 3 Mar and the geomagnetic field reached minor storm levels for 12 hours, active levels for9 hours on 2-4 Mar. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 26, 28 Feb and 3,4 Mar.

Within next week, solar activity is expected to be mainly very low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach minor storm levels on 5-6 Mar and be quiet to unsettled during other periods. The greater than 2 MeV electron flux at geosynchronous orbit will maintain at minor storm levels on 5 Mar.
