Weekly Forecast

During the past 24 hours, solar activity was low. One sunspot region was on the visible disk with two C-class flares produced. The solar wind speed maintained at about 510 km/s. The geomagnetic field was quiet to unsettled.

Within the next three days, solar activity is expected to be very low to low. The geomagnetic field is expected to be mainly quiet to unsettled.

During the last week, solar activity was very low. Six sunspot regions were on the visible disk without C-class and above flare produced. Due to the continuous effect of CME on 24 Nov, the solar wind speed reached a peak of about 410 km/s on 28-29 Nov. The geomagnetic field was at active levels for 6 hours. Due to the effect of a coronal hole high speed stream , the solar wind speed increased to a maximum about 540 km/s on 1 Dec. The geomagnetic field was at minor storm levels for 3 hour on 30 Nov and at active levels for 9 hours on 1 Dec. The geomagnetic field was quiet to unsettled for the rest time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 2 Dec.

Within the next week, solar activity is expected to be very low. Due to the effect of the CME on 29 Nov and the coronal hole high speed stream, the geomagnetic field is expected to reach minor storm levels on 3 Dec and reach isolated active levels on 4-5 Dec. It will be mainly quiet to unsettled for the rest time.
