:Product: Forecast Discussion :Issued: 2026 Jun 14 1230 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity continued at low levels. Region 4465 (N08W04, Cao/beta) developed a few rudimentary leader spots, and new Region 4468 (N10E46, Cro/beta) was numbered this period. The remaining regions were either stable or in decay. The strongest flare of the period was a C2.5/Sf at 13/1309 UTC associated with a filament eruption near S21W73. The subsequent CME, first observed in LASCO C2 imagery off the SW at 13/1326 UTC, is expected to miss Earth. .Forecast... Solar activity is expected to remain at low levels through 16 Jun, with a slight 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 1,519 pfu. The greater than 10 MeV proton flux remained at background levels. .Forecast... The greater than 2 MeV electron flux is likely to reach high levels on 14-16 Jun. The greater than 10 MeV proton flux is expected to continue at background levels through 16 Jun. Solar Wind .24 hr Summary... Solar wind parameters reflected the continued influence of a negative polarity CH HSS, with some lingering CME enhancements early in the period. Total field strength reached 7 nT, and the Bz component varied between +/-5 nT. Solar wind speeds gradually decreased from a peak near 625 km/s early in the period to a low of around 475 km/s by the end of the period. .Forecast... The solar wind environment is expected to remain mildly enhanced over 14-15 Jun under continued, but waning -CH HSS influences. An additional enhancement is likely on 16 Jun due to the anticipated glancing-blow arrival of a CME from 12 Jun. Geospace .24 hr Summary... The geomagnetic field was at mostly quiet to unsettled levels, with an isolated active period, under -CH HSS and CME influences. .Forecast... The geomagnetic field is expected to be at quiet to unsettled levels, with a chance for active conditions, on 14-15 Jun as -CH HSS influences slowly diminish. Periods of active conditions are likely on 16 Jun due to the anticipated glancing-blow arrival of a CME that left the Sun on 12 Jun.
