750 FXXX12 KWNP 050031 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jul 05 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 remained low. Only low-level C-class X-ray activity was observed. All numbered active regions on the visible disk were either mostly stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low 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 waning CME influences during the period. The total magnetic field strength was observed between 7-13 nT. The Bz component reached as far south as -10 nT. Solar wind speeds varied between ~330-425 km/s. .Forecast... Solar wind parameters are expected to remain mildly elevated over 05-07 Jul as residual CME influences subside and are followed by negative polarity coronal hole influence. Geospace .24 hr Summary... The geomagnetic field reached an isolated active period in response to waning CME influence. .Forecast... The geomagnetic field is expected to be at unsettled to active levels early on 05 Jul due to residual CME effects. Quiet to unsettled levels are expected to prevail by late 05 Jul and continue into 06-07 Jul in response to negative polarity CH HSS influences.
