Solar Forecast

(last updated 27 Feb 2020 23:30 UT)

28 Feb 29 Feb 01 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, 27 February. There are currently no active regions on the visible disc. Two active regions may rotate onto the disc in the next day. A small ejection was observed on the west limb at 0912 UT in LASCO C2 images. The ejection was not observed in STEREO A images and so is unlikely to be geoeffective. The solar wind speed ranged between 330 to 380 km/s, total IMF peaked at 4 nT, while the IMF north-south component ranged between +3/-3 nT. The IMF direction was variable while temperature and density showed no disturbances. Very Low levels of solar activity are forecast for the next three days, 28 February to 1 March. The wind speed and IMF may become mildly elevated late on 28 February due to the effects of a small coronal hole. The effects of another coronal hole may be evident late on 1 March.

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