Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was one active region AR2770 on the visible disk. The solar wind speed decreased to about 400 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 very low. The geomagnetic field is expected to be mainly quiet. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain at minor storm levels on 8 Aug.

During last week, solar activity was very low. There was 4 sunspot regions AR2767- AR2770 on the visible disk. The F10.7 index ranged from 72 sfu to 73 sfu. Due to the effects of coronal hole high speed stream, the solar wind speed reached a peak of about 720 km/s and the geomagnetic field reached active levels for 6 hours on 3-4 Aug and quiet to unsettled levels for the rest time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 6 Aug.

Within the next week, solar activity is expected to be very low. The geomagnetic field is expected to be mainly quiet. The greater than 2 MeV electron flux at geosynchronous orbit will reach minor storm levels on 7-8 Aug.
