496 FXXX12 KWNP 050031 DAYDIS :Product: Forecast Discussion :Issued: 2024 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 reached moderate levels with R1 (Minor) conditions observed. An M1.0 flare and type-II radio sweep at 04/1425 UTC originated from the vicinity of Region 3723 (S18W75), which remained spotless. An M1.4 flare and type-II sweep at 04/2005 UTC originated in the vicinity of Region 3730 (S18W85), another spotless region. The remainder of the period saw slight increases in C-class flare activity and x-ray background flux. Region 3733 (N05W41, Dai/beta) increased in size and total spot count throughout the period while Region 3737 (S14W76,Dao/beta) underwent minor growth after emerging the previous period. The remaining regions were stable or in decay. No Earth-directed CMEs were observed. .Forecast... Solar activity is expected to be low over 05-07 Jul with a chance for M-class (R1-R2/Minor-Moderate) flares. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was normal to moderate 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 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... The solar wind environment was enhanced throughout the period due to the influences of a passing CME. Total field strength reached 11 nT and the Bz was sustained southward, by as much as -8 nT, between roughly 04/1030-1300 UTC. Solar wind speed ranged from 320-380 km/s. Phi angle was mostly positive. .Forecast... Disturbed solar wind conditions due to CME influences are expected to continue into 05 Jun. Nominal solar wind conditions are expected to prevail on 06-07 Jul. Geospace .24 hr Summary... The geomagnetic field was quiet and unsettled. .Forecast... Quiet to unsettled levels are expected on 05 Jul, with a chance for active conditions, due to CME influences. Mostly quiet conditions are expected to prevail over 06-07 Jul.
