309 FXXX12 KWNP 300031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jun 30 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 was low with C-class flares observed. Growth was observed in Region 3729 (S05E29, Eao/beta), and new Regions 3733 (N05E28, Cao/beta), 3734 (N08E70, Cao/beta), and 3735 (N17E75, Hsx/alpha) were numbered. The remaining regions were largely unchanged from the previous period, and were generally quiet. Other activity included a CME (off the SW in LASCO C2 imagery at 29/0336 UTC) associated with an eruption from Region 3719 (S16W69, Cso/beta) at 29/0312 UTC. This CME is not Earth-directed. A large (~30 degree) filament centered near S28W18 lifted-off at around 29/1430 UTC. The associated CME, seen in LASCO C2 imagery off the SW at 29/1600 UTC, is likely to result in a glancing-blow on 03 Jul. .Forecast... Solar activity is expected to be low over 30 Jun-02 Jul with a chance for M-class (R1/R2-Minor/Moderate) events. 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 be at normal to moderate levels over 30 Jun-02 Jul. The greater than 10 MeV proton flux is expected to persist at background levels through 02 Jul. Solar Wind .24 hr Summary... The solar wind environment remained slightly enhanced this period following CME passage on 28 Jun. Total field strength ranged 6-11 nT and Bz varied +10/-6 nT. Solar wind speeds decreased from 500 km/s to 400 km/s over the course of the day. Phi was predominately positive. .Forecast... Slightly enhanced solar wind conditions are expected to persist into 30 Jun. An additional enhancement is expected over 01-02 Jul due to the anticipated arrival of CMEs from 26-27 Jun. Geospace .24 hr Summary... The geomagnetic field ranged from quiet to active levels. .Forecast... Quiet to unsettled conditions are expected to prevail on 30 Jun. Unsettled to active conditions are expected on 01-02 Jul due to the anticipated arrival/passage of CMEs from 26-27 Jun.
