Weekly Forecast

During the past 24 hours, solar activity was moderate. Five sunspot regions were on the visible disk with three M-class and several C-class flares produced. The solar wind speed decreased to about 420 km/s. The geomagnetic field was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit maintained at minor storm levels.

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 reach minor storm levels on 17-18 Aug due to the effect of a recurrent coronal high speed stream and CME from 14 Aug. It'll be mainly quiet to unsettled on other periods of time. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain at minor storm levels on 16 Aug.

During the last week, solar activity was very low to low. Nine active sunspot regions (AR3068, AR3071-AR3078) were on the visible disk with 9 C-class flares produced. The F10.7 index fluctuated between 108 sfu and 116 sfu. Due to the effect of coronal hole high speed stream, the solar wind speed reached the peak value of about 600 km/s on 7-9 Aug, and the geomagnetic field was at moderate storm levels for 3 hours, minor storm levels for 9 hours and active levels for 33 hours. Due to the effect of coronal hole high speed stream, the solar wind speed maintained at about 550 km/s on 11 Aug, and the geomagnetic field was at active levels for 6 hours. The geomagnetic field was at quiet to unsettled levels for the rest of the time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 9-11 Aug.

Within the next week, solar activity is expected to be mainly low with a chance for M-class flares produced. The geomagnetic field is expected to reach isolated active or minor strom levels on 17-18 Aug due to the effect of coronal hole high speed stream. It will be quiet to unsettled on other time. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain at minor storm levels on 12-15 Aug.
