During the past 24 hours, solar activity was very low. There were no active regions on the visible disk, without C-class and above flares produced. Due to the continuous effect of the coronal hole high speed stream, the solar wind speed maintained at about 500 km/s. The geomagnetic field reached minor storm levels for 3 hours.The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm level.
Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to be mainly quiet to unsetted on 11-12 Oct and reach isolated active levels on 13 Oct due to the effect of a new coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit will maintain at minor storm levels.
