195 FXXX12 KWNP 070031 DAYDIS :Product: Forecast Discussion :Issued: 2025 Jun 07 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 remained at low levels. Region 4105 (S14E34, Eai/beta-gamma) remained the largest, most magnetically complex and productive region. It produced the largest flare of the period, a C4.5 flare at 06/1702 UTC. The region of emerging flux in the SE quadrant (S17E10) was assigned active region number 4107, and was initially classified as a Cro/Beta type. The remaining numbered regions were steady or decaying. Emerging flux was noted in a few areas scattered around the visible disk, but at the time of this writing, none were persistent enough to warrant numbering. CMEs were observed emerging from the south and northeast (06/1112 UTC in LASCO/C2) during the period. Neither was judged geoeffective. .Forecast... Solar activity is expected to be low with a chance for M-class flares (R1-R2/Minor-Moderate) on 07-09 Jun. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels with a peak flux of 5,178 pfu observed at 06/1615 UTC. The greater than 10 MeV proton flux was near background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at moderate to high levels through 09 Jun. The greater than 10 MeV proton flux is expected to continue at or near background levels. Solar Wind .24 hr Summary... Solar wind parameters were quiescent. Total magnetic field strength was mostly at or below 5 nT, with Bz generally +/-4. Solar wind speed was steadily decreasing from 500-400 km/s. Phi angle was mostly negative. .Forecast... Modest enhancements from a slow, glancing-blow CME that left the Sun on 03 Jun are possible around mid-to-late 07 Jun, and these would be compounded by the continued fast stream influence from the southern hemisphere coronal hole. Geospace .24 hr Summary... The geomagnetic field was at quiet levels. .Forecast... The geomagnetic field is expected to begin at quiet to unsettled levels on 07 Jun as HSS activity continues. G1 (Minor) storm levels are likely mid-to-late on 07 Jun with the anticipated onset of a CME that left the Sun on 03 Jun. On 08-09 Jun, unsettled to active levels are expected.
