Weekly Forecast

During the past 24 hours, solar activity was low. There were three active regions on the visible disk, with a C2.1 flares produced from AR2715. The solar wind speed decreased slowly to about 370 km/s. The geomagnetic field was quiet.

Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to be mainly quiet.

During last week, solar activity was at low levels on 21 Jun, and very low levels on other periods. There was three active regions on the visible disk (Region 2713 - 2715). One C-class flare was produced by AR2715. The F10.7 index increased from 71 sfu to 82 sfu. Due to the effect of the recurrent coronal hole high speed stream, the solar wind speed reached a peak of 590 km/s on 18 Jun, and the geomagnetic field reached minor storm levels for 3 hours and active levels for 9 hours. It was quiet to unsettled on other periods.

Within the next week, solar activity is expected to be very low to low. Due to the effect of the recurrent coronal hole high speed stream, the geomagnetic field is expected to reach isolated minor storm levels on 27-28 Jun. It will be quiet to unsettled for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit is expect to reach minor storm levels on 28 Jun.
