Weekly Forecast

During the past 24 hours, solar activity was very low with no C-class and above flares produced. There was one active region on the visible disk. The solar wind speed increased to about 510km/s. The geomagnetic field was active for 3 hours, and quiet to unsettled during other periods of time.

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

During last week, solar activity was very low. There were three active regions on the visible disk, numbered AR2662 - AR2664. The F10.7 index flutuated between 74 sfu and 75 sfu. Due to the effects of a coronal hole high speed stream, the solar wind reached a peak of 630 km/s on 16 Jun, and the geomagnetic field was at minor storm levels for 6 hours, active levels for 15 hours on 16-17 Jun, and quiet to unsettled levels for the time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 19-21 Jun.

Within the next week, solar activity is expected to be very low. Due to the effects of the two coronal hole high speed streams, the geomagnetic field is expected to reach active levels on 23-24 Jun, and be quiet to unsettled for other time.
