DAILY REPORTS

Space Environment Summary

During the past 24 hours, solar activity was low. Six sunspot active regions were on the visible disk without M-class or above flare produced. The solar wind speed maintained at about 320 km/s. The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit maintained at minor storm levels.

Space Environment Forecast

Within the next three days, solar activity is expected to be mainly low with a slight chance for M-class flares. The geomagnetic field is expected to reach isolated active levels due to the effect of a recurrent coronal hole high speed stream and will be mainly quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain at minor storm levels on 25-26 May.
