Solar Forecast

(last updated 13 Feb 2026 23:30 UT)

14 Feb 15 Feb 16 Feb Activity R0, chance of R1 R0, chance of R1 R0, chance of R1 Fadeouts Possible Possible Possible 10.7cm/SSN 115/66 115/66 110/60 COMMENT: Solar flare activity on UT day 13-Feb was at the R1 level due to an M1.0 flare at 13/0858UT. There are currently four numbered and one unnumbered sunspot regions visible on the solar disk. AR4373 (S07W24, beta) was responsible for the M1.0 flare observed during the UT day, but appears to have decayed slightly and is magnetically simple. AR4374 (N10E15, beta) showed some minor spot development over the day. An unnumbered region has developed at around S10W17 with beta magnetic classification. All other sunspot regions are either stable or in decay. Solar flare activity is expected to be at the R0 level over 14-16 Feb, with a chance of R1. S0 solar proton conditions were observed on UT day 13-Feb. S0 solar proton conditions are expected over 14-16 Feb. No Earth-directed coronal mass ejections (CMEs) have been observed. A narrow northwest directed CME is visible from 13/0936UT in SOHO and STEREO-A imagery. This event is associated with an on disk eruption associated with the M1.0 flare at 13/0858UT. This CME was modelled and is not considered geoeffective. The solar wind speed increased slightly over 13-Feb, mostly ranging between 355 and 490 km/s. The wind speed is currently at around 475 km/s. The peak total interplanetary magnetic field strength (IMF, Bt) was 9 nT and the north-south IMF component (Bz) range was -9 to +9 nT. The solar wind speed is expected to mostly remain near background levels on 14-Feb. An increase is expected over 15-16 Feb due to a narrow equatorial coronal hole currently rotating towards a geoeffective position.
