Solar Forecast

(last updated 18 Jan 2018 23:30 UT)

19 Jan 20 Jan 21 Jan Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 71/6 71/6 71/6 COMMENT: Solar activity was very low today (UT day 18 January). There is one sunspot region (2696, S12W15 at 2300UT/18 January) on the solar disk visible from the earth. This is a stable region with beta magnetic configuration. This region produced a B9.7 flare that peaked at 0735UT. Although the region 2696 group seems stable, but due to the differential rotation between the two opposite polarity parts of the group, there is slightly increased chance of a C-class flare from this region. Solar wind speed stayed mostly between 310 and 340 km/s today. The north-south component of IMF, Bz, varied mostly between +/-3 nT today, whereas the total IMF, Bt, mostly varied between 1 and 5 nT during this time. Very low levels of solar activity may be expected for the next three days (19 to 21 January) with a slight chance of isolated C-class flare.

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