817 FXXX12 KWNP 041231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 04 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 low levels with Region 3729 (S05W33, Fai/beta-gamma) contributing to the majority of the low level C-class activity. Slight decay was observed in Region 3729. Slight growth and development was observed in Region 3733 (N06W35, Dai/beta) and newly numbered 3737 (S14W70, Dso/beta). No Earth-directed CMEs were observed. .Forecast... Solar activity is expected to be low over 04-06 Jul with a chance for M-class (R1-R2/Minor-Moderate) flares. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels with a peak flux of 1,190 pfu at 03/1905 UTC due to residual CME effects. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to reach high levels on 04 Jul and then return to normal to moderate levels on 05-06 Jul. The greater than 10 MeV proton flux is expected to persist at background levels. Solar Wind .24 hr Summary... Solar wind parameters became slightly enhanced after 04/0055 UTC, likely due to glancing effects from a CME that occurred in late Jun. Total field increased to 10 nT with the Bz component between +4/-7 nT. Solar wind speed was ranged from 313-412 km/s. Phi angle was mostly positive. .Forecast... Solar wind parameters are likely to continue to be slightly enhanced on 04-05 Jul. A return to nominal solar wind conditions is expected on 06 Jul. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... Quiet to unsettled levels are expected on 04-05 Jul, with a chance for isolated active periods. A return to mostly quiet conditions is expected on 06 Jul.
