DAILY REPORTS

Space Environment Summary

During the past 24 hours, solar activity was low. Four sunspot active regions were on the visible disk without any M-class or above flares produced. Due to the continuous effect of the recurrent coronal hole high speed stream, the solar wind speed maintained at about 500 km/s and the geomagnetic field reached minor storm level for 3 hours and active levels for 6 hours. It 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. The geomagnetic field is expected to be mainly quiet to unsettled.
