Weekly Forecast

During the past 24 hours, solar activity was very low. Four sunspot regions were on the visible disk without C-Class and above flare produced. Due to the continuous effects of the coronal hole high speed stream, the solar wind speed reached a peak of about 610 km/s. The geomagnetic field reached minor storm levels for 6 hours and active levels for 6 hours.

Within the next three days, solar activity is expected to be very low to low. Due to the effects of the coronal hole high speed streams, the geomagnetic field is expected to reach isolated active levels on 29-30 Nov and reach minor storm levels on 1 Dec.

During the last week, solar activity was moderate on 19 Nov and very low to low on other days. Six active sunspot regions (AR3147-AR3152) were on the visible disk with one M1.6 flare and 35 C-class flares produced. No solar proton events occurred. The F10.7 index ranged between 110 sfu and 119 sfu. Due to the effect of a recurrent coronal hole high speed stream, the solar wind speed reached a peak of about 460 km/s on 20-21 Nov and the geomagnetic field reached active levels for 6 hours, with quiet to unsettled levels for the rest of the time.

Within the next week, solar activity is expected to be mainly low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach isolated active levels on 25 Nov. Due to the effect of another recurrent coronal hole high speed stream, the geomagnetic field is expected to reach isolated active levels on 29 Nov-1 Dec, quiet to unsettled levels for the rest of the time.
