Solar Forecast

(last updated 23 Mar 2017 23:30 UT)

24 Mar 25 Mar 26 Mar Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 75/13 75/13 75/13 COMMENT: Solar activity has been very low today (23 March, UT). A B3.3 flare was observed at 1858 UT from region 2643(N08E50). As anticipated, the effect of the recurrent coronal hole is continuing to keep the solar wind stream strong. The solar wind speed varied between 600 km/s and 700 km/s during most parts of the UT day today. The north-south component of the IMF, Bz was at around -3 nT at the start of the day and then gradually rose to around +6 nT by the time of this report. The effect of this coronal hole is expected to keep the solar wind stream strong for the next two days. Very Low levels of solar activity are expected for the next 3 days (24 to 26 March) with a slight chance of C-class activity.

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