Solar Forecast

(last updated 23 Jan 2017 23:35 UT)

24 Jan 25 Jan 26 Jan Activity Very low to low Very low to low Very low to low Fadeouts None expected None expected None expected 10.7cm/SSN 85/27 82/23 80/20 COMMENT: Solar activity was Very Low over the last 24 hours. No Earth-directed CMEs were observed in available LASCO imagery. Of the 3 notable regions currently on the visible disk (NOAA 2626,2627 & 2628), all appear to have reduced in size over the last 24 hours. The solar wind speed gradually declined from ~470km/s at 00UT to be ~400km/s at the time of this report. The north-south component of the IMF (Bz) ranged between -5nT and 4nT over the UT day. Solar wind parameters are returning to ambient levels and should remain so for the next 3 days, after which solar wind speed is expected to increase due to the influence of a high speed solar wind stream from a recurrent equatorial located positive polarity coronal hole. Solar activity is expected to be Very Low to Low with a slight chance of M-class flares for the next 3 days.

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