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 flare produced. The solar wind speed decreased to about 400 km/s. The geomagnetic field was quiet.

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 will be mainly at quiet to unsettled levels on 19 Oct, and active to minor storm for isolated time periods on 20-21 Oct due to the effect of the recurrent coronal hole high speed stream.
