During last week, solar activity was very low. There was one active region on the visible disk, without C class and above flares produced. The F10.7 index ranged from 69 sfu to 73 sfu. Due to the effect of the recurrent coronal hole high speed stream, the solar wind speed reached the peak of about 620 km/s on 1 Mar and the geomagnetic field was at minor storm for 3 hours, and at active levels for 15 hours on 1 Mar. The greater than 2 MeV electron flux at geosynchronous orbit reached moderate storm levels on 2-3 Mar, and minor storm levels on 4-7 Mar.
Within the next week, solar activity is expected to be very low to low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active levels for 8 Mar and 12-13 Mar. It will be mainly quiet to unsettled for the rest of time.

The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm levels on 9-11 Mar.
Within the next week, solar activity is expected to be very low. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach active levels for 15 Mar and 20 Mar. It will be mainly quiet to unsettled for the rest of time.

During last week, solar activity was very low to low. There were two active regions (AR2735 and AR2736) on the visible disk. A C4-class flare associated with a partial CME was produced from AR2736 on 20 Mar. The F10.7 index increased from 70 sfu to 80 sfu. Due to the effect of a recurrent coronal hole high speed stream, the solar wind speed increased to about 460 km/s on 16-17 Mar. The geomagnetic field reached minor storm level for 3 hours and active levels for 9 hours on 16-17 Mar, and quiet to unsettled levels for the rest time.
Within the next week, solar activity is expected to be low. The geomagnetic field is expected to reach minor storm levels on 23-24 Mar due to the arrival of CME produced on 20 Mar. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach minor storm levels for 27-28 Mar. It will be mainly quiet to unsettled for the rest of time.
