DAILY REPORTS
 
Space Environment Summary
During the past 24 hours, solar activity was low. Nine sunspot regions were on the visble disk without any M-class or above flares produced. The solar wind speed decreased to about 430 km/s. The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit remained at minor storm levels.

Space Environment Forecast
Within next three days, the solar activity will be low to moderate with chances for M-class flares. The geomagnetic field is expected to be mainly quiet to unsettled with isolated active periods on 22 Jul due to the effect of the recurrent coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit will remain at minor storm levels.
