DAILY REPORTS
 
Space Environment Summary
During the past 24 hours, solar activity was low. Nine active sunspot regions were on the visble disk without M-class or above flares produced. The solar wind speed increased to the peak of about 480 km/s. The geomagnetic field was at quiet to unsettled levels.

Space Environment Forecast
Within the next three days, solar activity is expected to be low to moderate with chances for M-class flares. Due to the effect of the recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active or minor storm levels on 2-3 Apr and it will be queit to unsettled on 4 Apr.
