DAILY REPORTS

Space Environment Summary

During the past 24 hours, solar activity was low. Six active sunspot regions were on the visible disk without M-Class flares produced. The solar wind speed decreased to about 430 km/s. The geomagnetic field was quiet.

Space Environment Forecast

Within the next three days, solar activity is expected to be low to moderate with a chance for M-class flares. The geomagnetic field is expected to be mainly at quiet to unsettled levels. The greater than 2 MeV electron flux at geosynchronous orbit will reach minor storm levels on 23-25 Aug.
