Solar Forecast

(last updated 22 Feb 2026 23:30 UT)

23 Feb 24 Feb 25 Feb Activity R0 R0 R0 Fadeouts None expected None expected None expected 10.7cm/SSN 112/63 115/66 118/70 COMMENT: Solar flare activity was at the R0 level during UT day 22-Feb, with no significant flares observed. The Sun is currently spotless, with no numbered or unnumbered active regions on the visible disk. Solar flare activity is expected to remain at the R0 level through 23-25 Feb, due to the lack of active regions on the visible disk. S0 solar radiation storm conditions were observed over the last 24 hours, with the solar proton flux remaining at background levels. S0 conditions are forecast over 23-25 Feb. No geoeffective Coronal Mass Ejections (CMEs) were observed over the past UT day. A far-side CME was visible in the GOES Compact Coronagraph (CCOR-1) from 22/1300UT. A filament eruption was also observed on the eastern limb at (S20E88), visible in SDO and GOES SUVI imaging from 22/1330UT. An associated CME from this eruption was observed from 22/1600UT, but has been modelled as missing the Earth. The solar wind increased to very strong levels over the last 24 hours due to an equatorial coronal hole high-speed wind stream. The windspeed began the day ranging from 500-550 km/s, and increased after 22/0800UT, and is currently ranging between 650-700 km/s. The interplanetary magnetic field strength (IMF, Bt) peaked at 15 nT, at the start of the UT day. The north-south component (Bz) of the magnetic field ranged between -10 and +11 nT, with a prolonged period of southward Bz observed between 22/0742UT and 22/0952UT. The solar wind is forecast to remain elevated over 23-24 Feb due to the coronal hole high-speed wind stream, before declining by 25-Feb as the coronal hole moves beyond a geoeffective position.
