Weekly Forecast

During the past 24 hours, solar activity was very low. There was no active region on the visible disk, without C-class and above flare produced. The solar wind speed maintained at about 340 km/s. The geomagnetic field was quiet to unsettled.

During last week, solar activity was at very low to low levels. There was no active region on the visible disk, with only one C1.6 flare produced from eastward limb on 6 July. The F10.7 index ranged from 72 sfu to 73 sfu. Due to the continous effect of the coronal hole high speed stream, the solar wind speed reached a peak of 524 km/s on 7 Jul. The geomagnetic field was at quiet to unsettled levels.

Within the next week, solar activity is expected to be mainly very low. Due to the effect of the coronal hole high speed stream, the geomagnetic field is expected to reach active levels on 15 Jul. It will be quiet to unsettled for the rest of time.
