419 FXXX12 KWNP 080031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 08 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 reached moderate levels. Low level M-class activity was observed late in the period from the SE limb. AR 3738 (S09E44, Ekc/beta-gamma) produced most of the C-class flare activity observed this period, and continued to show signs of growth. The remaining regions were mostly stable or in gradual decay. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low over 08-10 Jul, with a chance for isolated M-class (R1-R2/Minor-Moderate) flare activity. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at normal to moderate levels over 08-10 Jul. The greater than 10 MeV proton flux is expected to persist at background levels through 10 Jul. Solar Wind .24 hr Summary... Solar wind parameters became slightly enhanced after 07/1200 UTC. Total field strength ranged 1-8 nT and Bz briefly reached as far south as -6 nT. Solar wind speeds were steady at around 300-350 km/s through 1200 UTC, and increased to a peak of around 400 km/s shortly after. The phi was positive through much of the period, and became variable after 07/1800 UTC. .Forecast... Slightly enhanced solar wind conditions are likely over 08-09 Jul in response to positive polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field reached unsettled levels late in the period due to a period of southward Bz. .Forecast... Quiet to unsettled conditions are expected over 08-09 Jul, with periods of active conditions likely on 08 Jul, in response to positive polarity CH HSS influences.
