During last week, solar activity was very low. There were two active regions, 2708 and 2709, on the visible disk, and no C-class and above flare produced. The F10.7 index fluctuated from 67 sfu to 70 sfu. Due to the effect of the recurrent coronal hole high speed stream, the solar wind speed reached a peak of 700 km/s on 5-9 May. The geomagnetic field was at moderate storm levels for 3 hours, minor storm levels for 9 hours and active levels for 27 hours. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 6-8 May and moderate storm levels on 9-10 May.
Within the next week, solar activity is expected to be very low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach minor storm levels on 16-17 May and be quiet to unsettled on other periods. The greater than 2 MeV electron flux at geosynchronous orbit is expected to maintain minor storm levels on 11-15 May.

During last week, solar activity was very low. There was one active region 2709 on the visible disk, and no C-class and above flare produced. The F10.7 index fluctuated from 69 sfu to 71 sfu. Due to the continuous effects of the recurrent coronal hole high speed stream, the geomagnetic field was at active levels for 15 hours, and quiet to unsettled levels on the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 11 May and minor storm levels on 12-17 May.
Within the next week, solar activity is expected to be very low.
