Weekly Forecast

During the past 24 hours, solar activity was high. Six active sunspot regions were on the visible disk with a M5.8-class flare produced by AR3110(N11E38), associated with a CME. The solar wind speed decreased to about 450 km/s. The geomagnetic field was quiet.

Within the next three days, solar activity is expected to be mainly moderate with a chance for M-Class flares. Due to the effect of the recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active or storm levels on 2-3 Oct. Due to the effect of CME produced on 1 Oct, the geomagnetic field is expected to reach active levels on 4 Oct.

During the last week, solar activity was moderate on 23 Sep, and low in other periods of time. Seven active sunspot regions (AR3102, AR3105, AR3107-AR3111) were on the visible disk with one M-class and several C-class flares produced. No solar proton events occurred. The F10.7 index ranged between 135 sfu and 146 sfu. The geomagnetic field was active levels for 3 hours on 24 Sep. Due to the effects of the coronal hole high speed stream and CMEs, the solar wind speed reached a peak value of about 580 km/s on 27 Sep, and the geomagnetic field was at moderate storm levels for 3 hours and active levels for 6 hours. The geomagnetic field was quiet to unsettled for the rest of time.

Within the next week, solar activity is expected to be mainly low to moderate levels. The geomagnetic field is expected to reach storm levels on 30 Sep-2 Oct due to the effects of the recurrent coronal hole high speed stream, and be mainly quiet to unsettled for the rest of time.
