Weekly Forecast

During the past 24 hours, solar activity was very low without C-class and above flare produced. There was one sunspot region, AR 2757, on the visible disk. The solar wind speed maintained at about 310 km/s. The geomagnetic field was quiet.

During last week, solar activity was very low. There were no sunspot regions on the visible disk without C-class and above flares produced. The F10.7 index ranged from 70 sfu to 72 sfu. Due to a coronal hole high speed stream, the solar wind speed reached a peak of about 350 km/s and the geomagnetic field reached unsettled levels for 9 hours on 21-23 Jan. It was quiet during other periods.
