Weekly Forecast

During the past 24 hours, solar activity was low. Seven sunspot regions were on the visible disk with several C-Class flares produced. The solar wind speed decreased to about 340 km/s. The geomagnetic field was quiet.

Within the next three days, solar activity is expected to be low to moderate. The geomagnetic field is expected to reach isolated active levels or minor storm levels on 6-7 Jul due to the coronal hole high speed stream. It is expected to be quiet to unsettled for other time.

During the last week, solar activity was mainly at low levels, and was at very low levels on 28 Jun and 30 Jun. Nine active sunspot regions (AR3034-AR3035, AR3038, AR3040-AR3045) were on the visible disk with 10 C-class flares produced, and no M or above class flares produced. The F10.7 index decreased from 115 sfu to about 92 sfu. Due to the effect of the coronal hole high speed stream, the solar wind speed reached the peak value of about 640 km/s on 26 Jun, and then gradully decreased to about 340km/s. The geomagnetic field reached minor storm levels for six hours and active levels for twenty-one hours. The geomagnetic field was at quiet to unsettled levels for the rest of time. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 27-30 Jun.

Within the next week, solar activity is expected to be mainly low. Due to the effect of the coronal hole high speed stream, the geomagnetic field will reach active levels for short periods on 6-7 Jul. It will be at quiet to unsettled levels during the other time.
