Solar Forecast

(last updated 28 Feb 2020 23:31 UT)

29 Feb 01 Mar 02 Mar 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 for UT day, 28 February. There are currently no active regions on the visible disc. Through UT day 28 February, the solar wind speed ranged between 320 to 370 km/s by mid-day and then showed a gradual increase to 460 km/s by 2300 UT. The total IMF (Bt) stayed relatively stable between 2 nT and 4 nT by 0700 UT and then showed fluctuations between 4 nT and 8 nT during the rest of the day. The north-south component of IMF (Bz) stayed predominantly southwards up to around -3 nT until 0700 UT and then showed fluctuations in the range +7/-6 nT. Solar wind parameters may stay enhanced during UT days 29 February to 2 March due to the effects of patchy coronal holes. Very Low levels of solar activity are forecast for the next three days, 29 February to 2 March.
