Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was no active region on the visible disk. Due to the effect of the coronal hole high speed stream and the CME observed on 9 Jul, the solar wind speed increased to about 400 km/s, the geomagnetic field reached isolated unsettled level.

Within the next three days, solar activity is expected to be very low. Due to the effect of the coronal hole high speed stream and the CME observed on 9 Jul, the geomagnetic field is expected to reach isolated active levels on 14 July, and to be mianly quiet on 15-16 July.

During last week, solar activity was very low. There was one sunspot region AR2766 on the visible disk. The F10.7 index ranged from 67 sfu to 70 sfu. Due to the effect of the coronal hole high speed stream, the solar wind speed reach a peak of about 530 km/s on 5 July. The geomagnetic field was quiet to unsettled.
