DAILY REPORTS

Space Environment Summary

During the past 24 hours, solar activity was low. Four active sunspot regions were on the visible disk without any M-class or above flares produced. Due to the effects of the recurrent coronal hole high speed streams, the solar wind speed reached a peak of about 570 km/s. The geomagnetic field reached minor storm levels for 6 hours and active levels for 6 hours, and was quiet to unsettled for the rest of the time.

Space Environment Forecast

Within the next three days, solar activity is expected to be mainly low with a chance for M-class flares. Due to the continuous effects of the recurrent coronal hole high speed streams, the geomagnetic field is expected to reach active to minor storm levels on 19-20 Aug, and be mainly at quiet to unsettled levels on 21 Aug.
