765 FXXX12 KWNP 140031 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jul 14 0030 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity decreased to low levels, with only C-class flare activity observed. Region 4140 (S15E46, Cao/beta) produced the majority of the C-class activity, the largest being a C9.0 flare at 13/0402 UTC. Regions 4138 (N29W39, Dao/beta) and 4139 (N22W04, Dai/beta) exhibited minor growth, while the remaining regions were mostly stable or in decay. No Earth-directed CMEs were detected in available coronagraph imagery. .Forecast... Solar activity is expected to be predominately low over 14-16 Jul, with a chance for M-class (R1-R2/Minor-Moderate) flare activity. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached moderate levels, and the greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels over 14-16 Jul. The greater than 10 MeV proton flux is expected to continue at background levels through 16 Jul. Solar Wind .24 hr Summary... Solar wind parameters continued to reflect positive polarity CH HSS influence. Total magnetic field strength reached 12 nT, and the Bz component briefly reached as far south as -10 nT. Solar wind speeds peaked near 725 km/s at 13/0750 UTC before gradually decreasing to around 575 km/s by the end of the period. The phi angle remained positive through most of the period. .Forecast... Elevated solar wind parameters are expected to persist over 14-16 Jul due to continued positive polarity CH HSS influence. Geospace .24 hr Summary... The geomagnetic field reached G1 (Minor) storm levels due to positive polarity CH HSS influence. .Forecast... Positive polarity CH HSS influence is expected to persist over 14-16 Jul. The geomagnetic field is likely to reach active levels on 14 Jul, with a chance for G1 (Minor) storming, followed by quiet to unsettled conditions and a chance for active periods on 15-16 Jul.
