During last week, solar activity was very low. There was no active region on the visible disk, without C-class and above flare produced. The F10.7 index ranged from 70 sfu to 71 sfu. Due to the coronal hole high speed stream, the solar wind speed reached about 390 km/s and the geomagnetic field reached unsettled levels for 3 hours on 11 Nov and quiet for the rest of the time.

Within the next week, solar activity is expected to be very low. Due to a coronal hole high speed stream, the geomagnetic field is expected to reach active levels on 16 Nov. Due to another coronal hole high speed stream, the geomagnetic field is expected to reach minor storm levels on 20-21 Nov and be quiet to unsettled for the rest of the time.
