222 FXXX12 KWNP 091231 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jul 09 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 at moderate levels due to an isolated M1.3 flare at 09/0425 UTC from newly numbered Region 4136 (N19E71, Dai/beta). This region was also responsible for yesterdays M2.4 flare at 08/0417 UTC. Slight growth was observed as it rotated around the NE limb, however an accurate magnetic classification could not be determined due to its proximity to the limb. New spots emerged in the NW quadrant and was numbered Region 4137 (N19W15, Cro/beta). Other activity included an approximate 17 degree filament eruption near N18W16 beginning at 09/0524 UTC. Modelling of a potential CME will commence as imagery becomes available. .Forecast... Solar activity is expected to be low with a further chance for M-class flares (R1-R2/Minor-Moderate) on 09-11 Jul, primarily due to the flare potential of Region 4136. 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 at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at moderate levels with a chance for high levels on 09-11 Jul. The greater than 10 MeV proton flux is expected to continue at background levels through 11 Jul. Solar Wind .24 hr Summary... Solar wind parameters reflected continued but waning influences from the negative polarity CH HSS. The total magnetic field has been trending down from 7 nT to around 4 nT, with the Bz component oscillating between +/-5 nT. Solar wind speeds have decreased from approximately 525 km/s to near 420 km/s. Phi angle has been mostly negative. .Forecast... Nominal solar wind conditions are anticipated to return on 09-11 Jul. Geospace .24 hr Summary... The geomagnetic field was quiet to unsettled. .Forecast... A return to mostly quiet conditions is expected on 09-11 Jul.
