Solar Forecast

(last updated 20 Apr 2014 23:30 UT)

21 Apr 22 Apr 23 Apr Activity Low to moderate Low to moderate Low to moderate Fadeouts Possible Possible Possible 10.7cm/SSN 165/119 160/114 150/105 COMMENT: Solar activity has been low with numerous C class flares from several sunspot regions, the greatest being a C6 from region 2033(N12W83) with an associated TypeII radio burst. Several CMEs, one of which is most likely associated with this event, were seen directed out the western limb. None are likely to be geoeffective. The CME from the M1 flare observed on the 18th arrived just after 10UT. There was no clear shock front. The IMF Bt increased to around 20nT but stayed mostly northward. The solar wind speed increased to a peak of around 700km/s and remain between 650-700 km/s. The high energy solar proton flux has dipped below alert thresholds and continues to fall. There is some chance of further M class flare activity over the next few days.

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