Weekly Forecast

During the past 24 hours, solar activity was low. Six sunspot regions were on the visible disk with two C-class flares produced. The solar wind speed decreased to about 470 km/s. The geomagnetic field was quiet.

Within the next three days, solar activity is expected to be mainly low. The geomagnetic field is expected to be quiet to unsettled.

During the last week, solar activity was moderate on 22, 25-26 Jan and low for the rest of time. Fifteen active sunspot regions (AR3184, AR3186, AR3190-3192, AR3194-3203) were on the visible disk with 6 M-Class flares and more than fifty C-Class flares produced. No solar proton events occurred. The F10.7 index decreased from 218 sfu to 151 sfu. Due to the effects of CME and coronal hole high speed stream, the solar wind speed reached a peak of about 550 km/s on 21-23 Jan, the geomagnetic field reached active levels for 6 hours on 21 Jan. Due to the effects of another coronal hole high speed stream, the solar wind speed reached a peak of about 550 km/s on 25-26 Jan. The geomagnetic field was at quiet to unsettled levels for the rest of the time.

Within the next week, solar activity is expected to be mainly low with a chance for M-Class flares. Due to the effect of a recurrent coronal hole high speed stream, the geomagnetic field is expected to reach isolated active to minor storm levels on 30-31 Jan, and quiet to unsettled levels for the rest of the time.
