Weekly Forecast

During the past 24 hours, solar activity was low. Seven sunspot regions were on the visible disk with two C-class flares produced. The solar wind speed maintained at about 540 km/s. The geomagnetic field was at quiet to unsettled levels.

Within the next three days, solar activity is expected to be low to moderate with a chance for M-class flares. The geomagnetic field is expected to be mainly quiet to unsettled.

During the last week, solar activity was very low to low. Eight sunspot regions were on the visible disk ( AR2924-AR2931) with 6 C-class flares produced. The F10.7 index ranged from 100 sfu to 107 sfu. Due to the effect of the coronal hole high speed stream, the solar wind speed reached a peak of about 550 km/s on 8-10 Jan and the geomagnetic field was at minor storm levels for 6 hours. The geomagnetic field was quiet to unsettled for the rest of time.

Within the next week, solar activity is expected to be low to moderate, with a chance for M-Class and above flares produced. Due to the effect of the recurrent coronal hole high speed stream, the geomagnetic field is expected to be at active to minor storm levels on 15-17 Jan. It will be mainly quiet for the rest of time.
