Solar Forecast

(last updated 31 Aug 2015 23:30 UT)

01 Sep 02 Sep 03 Sep Activity Very low to low Very low to low Very low to low Fadeouts None expected None expected None expected 10.7cm/SSN 85/27 80/20 80/20 COMMENT: The solar activity was at low levels for the UT day, 31 Aug. Region 2403 produced only one significant C-class solar flare peaking at 31/0522UT from the West limb. No earth directed CMEs were observed on the SOHO LASCO coronagrams images for the UT day. The 2-day outlook (1-2 Sep) is for very low solar activity with some chance of C class flares. During the last 24 hours, the solar wind dropped from 450 to 350 km/s. The Bz component of IMF fluctuated between -/+5 nT and Bt was mainly constant at 6 nT throughout the last 24 hours. The solar winds are expected to elevate over the next 24 hours (1 Sept) due to sector boundary crossing followed by the possible influence of a positive polarity equatorial coronal hole taking a geoeffective position on the solar disk. The solar winds are expected to remain elevated on 2 Sep due to the high speed streams emanating from the coronal hole.

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