Weekly Forecast

During the past 24 hours, solar activity was very low. Three sunspot regions were on the visible disk without C-class and above flare produced. The solar wind speed maintained at about 510 km/s. The geomagnetic field was at active levels for 9 hours and quiet to unsettled levels for the rest of time.

Within the next three days, solar activity is expected to be very low. Due to the effect of the CME on 29 Nov and the coronal hole high speed stream, the geomagnetic field is expected to reach active to minor storm levels on 3 Dec and to be at quiet to unsettled levels for the rest of time.

During last week, solar activity was very low. Three sunspot active regions (2896-2898) were on the visible disk without C-class and above flare produced. The F10.7 index ranged between 78 sfu and 94 sfu. Due to the effect of a recurrent coronal hole high speed stream, the solar wind speed increased to about 690 km/s on 21 Nov and the geomagnetic field was at quiet to unsettled levels.

Within next week, solar activity is expected to be mainly very low to low. The geomagnetic field is expected to reach isolated active levels on 27-28 Nov due to the effect of a coronal hole high speed stream and CME, and be mainly quiet to unsettled for the rest time.
