Solar Forecast

(last updated 19 Mar 2019 23:30 UT)

20 Mar 21 Mar 22 Mar 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 the UT day 19 March. Currently there is one spotted region on the visible disc, AR2735. Solar activity is expected to remain Very Low for the next 3 UT days, 20-22 March, with a slight chance for C-class flares. No Earth directed CMEs were observed in the available imagery. The solar wind speed was near its background levels up to 19/1330 UT, then it increased to 410 km/s. At the time of this report the solar wind speed is near 400 km/s. The total IMF (Bt) ranged between 1 nT and 3 nT up to 19/0820 UT, then it abruptly increased to 7 nT and then varied in the range 4-7 nT. After 0820 UT the north-south component of IMF (Bz) was oscillating between +7 nT and -6 nT. Solar wind speed is expected to remain moderately enhanced during the next UT day, 20 March, due to the high-speed solar wind stream from the recurrent equatorial coronal hole.

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