Solar Forecast

(last updated 23 Oct 2016 23:30 UT)

24 Oct 25 Oct 26 Oct Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 76/14 74/11 73/9 COMMENT: Solar activity was very low over the last 24 hours. Solar wind speed gradually increased from around 370 to 460 km/s by 1000 UT today (23 October) and then dropped down to around 420 by 2300 UT. The north-south component of IMF, Bz, mostly varied between +/-6 nT today, staying slightly southwards for relatively longer periods of time during the second half of the UT day. Bt varied mostly between 5 and 8 nT during the day. Solar activity is expected to stay at very low levels for the next three days (24, 25 and 26 October) with some chance of C-class activity. The effect of a positive polarity coronal hole is expected to keep the solar wind stream strong for the next two days.

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