Weekly Forecast

During the past 24 hours, solar activity was low. Seven sunspot regions were on the visible disk with one C-Class flares produced. The region 3153(S16E08) decreased to the area of 660 with a Beta magnetic type. 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 mainly low with a chance for M-Class flares produced. The geomagnetic field is expected to reach active or storm levels on 8 Dec due to the effects of the coronal hole high speed streams, it will be quiet to unsettled on other periods of time.

During the last week, solar activity was moderate on 1 Dec and very low to low on other days. Seven active sunspot regions (AR3147, AR3149, AR3152-AR3155) were on the visible disk with one M1.0 flare and 17 C-Class flares produced. No solar proton events occurred. The F10.7 index increased from 107 sfu to 119 sfu. Due to the effects of the recurrent coronal hole high speed streams, the solar wind speed reached a peak of about 610 km/s and the geomagnetic field reached active levels for 15 hours on 25-26 Nov. The solar wind speed reached a peak of about 740 km/s and the geomagnetic field reached minor storm levels for 15 hours and active levels for 48 hours on 27 Nov-1 Dec. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 30 Nov and 1 Dec.

Within the next week, solar activity is expected to be mainly low with a chance for M-Class flares produced. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach isolated active or storm levels on 5-6 Dec, quiet to unsettled levels for the rest of the time. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach minor storm levels on 2-4 Dec.
