Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was no active region on the visible disk. The solar wind decreased to about 420 km/s. The geomagnetic field was at quiet to unsettled levels.

Within the next three days, solar activity is expected to be very low. The geomagnetic field is expected to be mainly at quiet to unsettled levels with possibility for isolated active levels on 17 Jun due to the effect of a recurrent coronal hole high speed stream.

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 68 sfu to 70 sfu. Due to the effects of the CME produced on 3 Jun and the recurrent coronal hole high speed stream, the solar wind speed reached a peak of 470 km/s and the southward component Bz of the interplanetary magnetic field reached a peak of -15 nT on 8-9 Jun. The geomagnetic field reached minor storm level for 3 hours and active levels for 6 hours on 8 Jun. Due to the effect of another recurrent coronal hole high speed stream, the solar wind speed reached a peak of 480 km/s ,and the geomagnetic field reached active levels for 3 hours on 13 Jun.

Within the next week, solar activity is expected to be very low. The geomagnetic field is expected to be mainly at quiet to unsettled levels with possibility for isolated active levels on 17-18 Jun due to the effect of a recurrent coronal hole high speed stream.
