During last week, solar activity was very low. There was no sunspot region on the visible disk, without C-class and above flares produced. The F10.7 index ranged from 68 sfu to 71 sfu. The solar wind speed reached a peak of about 460 km/s on 12 Apr. The geomagnetic field was quiet to unsettled.
Within the next week, solar activity is expected to be very low. The geomagnetic field is expected to reach isolated active levels on 18-19 Apr due to the effect of a coronal hole high speed stream. It will be quiet to unsettled for the rest of the time.

During last week, solar activity was very low. There was no sunspot region on the visible disk, without C-class and above flares produced. The F10.7 index ranged from 68 sfu to 71 sfu. Due to the effect of CME produced on 15 Apr, the solar wind speed reached a peak of about 380 km/s, the southward component Bz of interplanetary magnetic field reached a peak of -15 nT. The geomagnetic field was at minor storm levels for 6 hours and active levels for 3 hours. Due to the effect of a coronal hole high speed stream, the solar wind speed increased to about 480 km/s. The geomagnetic field was at active levels for 3 hours. It was at quiet to unsettled levels for the rest of time.
Within the next week, solar activity is expected to be very low. The geomagnetic field is expected to reach isolated active levels on 26-27 Apr due to the effect of a coronal hole high speed stream. It will be quiet to unsettled for the rest of the time.

During last week, solar activity was very low. There were three sunspot regions (AR2760, AR2761 and AR2762) on the visible disk, without C-class and above flares produced. There were two CMEs observed during last week. One is from a filament eruption in the north east on 27 Apr, and another was observed on 29 Apr. The F10.7 index ranged from 69 sfu to 71 sfu. The geomagnetic field was quiet to unsettled.
Within the next week, solar activity is expected to be mainly at very low levels. Due to the combined effect of the coronal hole high speed stream and the CME on 29 Apr., the geomagnetic field is expected to reach isolated active levels on 3-4 May and to be quiet to unsettled for the rest of time.
