196 FXXX12 KWNP 060031 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jul 06 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 was at low levels. Region 4130 (S11E03, Cro/beta) produced an impulsive C1.5/Sf flare at 05/1218 UTC. Shortly after, this region produced an impulsive C1.3/Sf flare at 1346 UTC. This region maintains a rudimentary penumbra configuration. Region 4127 (S19W47, Cso/beta) grew slightly in length. The remaining 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 06-08 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 06-08 Jul. The greater than 10 MeV proton flux is expected to persist at background levels through 08 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 5-14 nT and the Bz component reached as far south as -12 nT. Solar wind speeds slowly increased from a low of about 390 km/s early in the period to a peak of around 485 km/s. The phi angle was in a predominately negative orientation. .Forecast... Solar wind parameters are expected to remain mildly elevated over 06-07 Jul due to negative polarity coronal hole influence. A return to nominal levels is expected by 08 Jul. 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 quiet to unsettled levels, with isolated active periods early on 06 July, due to negative polarity coronal hole influence. Conditions are expected to return to predominantly quiet to unsettled levels for the remainder of 06-07 July, becoming mostly quiet by 08 Jul.
