385 FXXX12 KWNP 220031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jun 22 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 decayed to low levels with C-class flare activity observed from Regions 3712 (S26W65, Ekc/beta-gamma), 3713 (S14W53, Ekc/beta-gamma-delta, 3716 (N10W59, Ekc/beta-gamma) and 3720 (S05E49, Cao/beta). Region 3713 produced most of the C-class flare activity observed this period and increased in size and spot count, and maintained a complex magnetic field structure. Regions 3712 and 3716 remained largely unchanged from the previous period. New Regions 3721 (N27E59, Hsx/alpha) and 3722 (S09E59, Dso/beta) were numbered this period. Region 3718 (N12, L=118) decayed to plage late in the period. Other activity included a Type II radio sweep (Est. 590 km/s) that was observed beginning at 21/2340 UTC and appeared to be associated with an event around the Suns E limb. No Earth-directed CMEs were detected in available imagery. .Forecast... M-class flares (R1-R2/Minor-Moderate) are likely over 22-24 Jun, with a slight chance for X-class flares (R3 or greater). Energetic Particles .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 at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels through 24 Jun. There is a slight chance for the greater than 10 MeV proton flux to reach S1 (Minor) levels over 22-24 Jun. Solar Wind .24 hr Summary... A nominal solar wind environment prevailed throughout the period. Total field ranged between 4-6 nT, the Bz component varied between +5/-3 nT and wind speeds decreased from 450 km/s to 375 km/s. The phi angle was positive. .Forecast... Negative polarity CH HSS influences and mildly enhanced solar wind conditions are likely over 22-23 Jun. Geospace .24 hr Summary... The geomagnetic field was at quiet levels throughout the period. .Forecast... Geomagnetic field activity is expected to be quiet and unsettled over 22-23 Jun, with periods of active conditions likely on 22 Jun, due to negative polarity CH HSS influences. Quiet conditions are expected on 24 Jun.
