Solar Forecast

(last updated 18 Nov 2019 23:31 UT)

19 Nov 20 Nov 21 Nov Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 70/5 70/5 70/5 COMMENT: Solar activity was very low for 18 November. There are currently no sunspots on the visible disc and no Earth-directed CMEs were observed in the available coronagraph imagery. Through UT day 18 November, the solar wind speed varied mostly between 350 and 370 km/s, the total IMF (Bt) between 2.3 and 4.1 nT, the north-south component of IMF (Bz) between +3/-3 nT and the solar wind particle density between 4 ppcc and 6 ppcc. Bz showed more variation during the late hours of the UT day. Solar wind stream is expected to remain at ambient levels through UT day 19 November and then show gradual strengthening through UT day 20 and possibly 21 November due to the effect of a positive polarity recurrent coronal hole. Very low levels of solar activity are expected for the next three UT days (19 to 21 November).

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