798 FXXX12 KWNP 061231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 06 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 low. The largest event was a C9.4 flare at 05/1904 UTC from a source just beyond the SW limb. Newly numbered Region 3739 (N03W08, Bxo/beta) was small and simple. Region 3738 (S10E62, Ekc/beta-gamma) was the most complex on the disk but produced relatively little activity this period. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low over 06-08 Jul, with a chance for isolated M-class (R1-R2/Minor-Moderate) flare activity. 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 steady 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 a weakly enhanced IMF that continued through the period. Total field strength ranged 3-9 nT and Bz varied +/-6 nT. Solar wind speeds were steady at around 350 km/s and the phi was positive. .Forecast... An ambient solar wind environment is expected to prevail on 06-07 Jul. Slightly enhanced solar wind conditions are likely to commence on 08 Jul in response to positive polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was quiet and unsettled. .Forecast... Geomagnetic field activity is expected to be mostly quiet over 06-07 Jul. Periods of active conditions are expected on 08 Jul due to the anticipated onset of positive polarity CH HSS influences.
