Weekly Forecast

During the past 24 hours, solar activity was low. Eight sunspot regions were on the visible disk without M-class or above flares produced. The solar wind speed maintained at about 400 km/s. The geomagnetic field was at quiet to unsettled levels.

Within the next three days, solar activity is expected to be mainly low with a chance for M-class flares. The geomagnetic field is expected to reach active levels for short periods on 7-8 Jun due to the effect of the CME from 4 Jun, mainly quiet to unsettled on 9 Jun.

During the last week, solar activity was moderate on 26, 28, 30-31 May and low for the rest of the time. Fourteen active regions (AR3310-3323) were on the visible disk with 8 M-class and 62 C-class flares produced. No solar proton events happened. The F10.7 index increased from 149sfu to 164sfu. The solar wind speed increased to about 480km/s on 1 Jun, the geomagnetic field reached active levels for 3 hours. It 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 26-27 May.

Within the next week, solar activity is expected to be mainly moderate with a chance for M-class and above solar flares. Due to the effect of the recurrent coronal high speed stream, the geomagnetic field is expected to reach isolated active levels on 2-3 Jun, mainly quiet to unsettled levels for the rest of the time.
