Solar Forecast

(last updated 26 Jan 2020 23:35 UT)

27 Jan 28 Jan 29 Jan Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 75/13 75/13 75/13 COMMENT: Solar activity was very low for UT day 26 January. There is currently one numbered region 2757(N03E05) visible on the solar disc. This region showed some growth and produced A flaring activity over the period. Another region has also rotated over the SE limb (no number yet). Very low levels of solar activity are expected for the next three UT days, 27-29 January. There is a chance of increased solar activity over the next coming days due to new development. A weak CME observed to west in STEREO coronagraph images around 26/0154 UT. Gaps in STEREO images and absence of SOHO LASCO coronagraph images between 25/2348 UT- 26/0524UT limited our ability to determine any earth directed component. No other Earth-directed CMEs were observed in the available coronagraph imagery. During the last 24 hours, the solar wind speed was at nominal levels, under 350 km/s. The total IMF Bt varied between 1-6 nT and the north-south component of the IMF (Bz) was in the range of +/-4 nT. The solar wind speed is expected to be near its background levels to slightly enhanced for 27-29 January due to weak coronal hole effects.

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