Solar Forecast

(last updated 22 Jan 2017 23:30 UT)

23 Jan 24 Jan 25 Jan Activity Low Low Low Fadeouts Possible Possible Possible 10.7cm/SSN 85/27 85/27 82/23 COMMENT: Solar activity was Very Low over the last 24 hours. No Earth-directed CMEs were observed in available LASCO imagery. Solar activity is likely to be Low with a chance of M-class flares for the next 3 days 23-25 Jan. The solar wind speed fluctuated around 500 km/s with a peak around 560 km/s at 22/0957UT. The IMF total strength peaked at 9.6 nT at 22/0222UT. Bz fluctuated between -5 to 9 nT in the first half of the UT day 22 Jan, then the fluctuations reduced to +/-3 nT. Solar wind speeds are expected to gradually decline over the next two days 23-24 Jan as the effects of the coronal hole high speed stream wanes. ACE EPAM data indicates an energetic ion enhancement event beginning 22/1645UT, which can be a precursor to increased geomagnetic activity over next 24-36 hours.

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