756 FXXX12 KWNP 051231 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jul 05 1230 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 was very low. All numbered active regions on the visible disk were either stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to reach low levels with a slight chance for R1-R2 (Minor-Moderate) radio blackouts over 05-07 Jul. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at normal to moderate levels over 05-07 Jul. The greater than 10 MeV proton flux is expected to persist at background levels through 07 Jul. Solar Wind .24 hr Summary... Solar wind parameters reflected the onset of negative polarity coronal hole influence during the period. The total magnetic field strength varied between 8-13 nT, and the Bz component reached as far south as -10 nT. Solar wind speeds steadily increased from a low of 330 km/s early in the period to a peak of around 480 km/s. .Forecast... Solar wind parameters are expected to remain mildly elevated over 05-07 Jul due to negative polarity coronal hole influence. Geospace .24 hr Summary... The geomagnetic field reached active levels in response to negative polarity coronal hole influence. .Forecast... The geomagnetic field is expected to reach active levels on 05 Jul, with quiet to unsettled levels expected over 06-07 Jul, due to negative polarity coronal hole influence.
