Solar Forecast

(last updated 21 Oct 2016 23:30 UT)

22 Oct 23 Oct 24 Oct Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 75/13 75/13 72/8 COMMENT: Solar activity was very low over the last 24 hours. Solar wind speed was around 400 km/s showing a slow decline during this period. The north-south component of IMF, Bz, mostly stayed positive up to around 3nT and Bt stayed around 4 nT on 21 October (UT day). Solar activity is expected to stay at very low levels for the next three days (22, 23 and 24 October) with some chance of C-class activity. A positive polarity coronal hole is expected to take a geoeffective position from late on 22 October. This may result in strengthening of solar wind stream from that time for the next few days.

Solar Activity levels are explained in the SWS Solar Terrestrial Glossary.
