569 FXXX06 KWNP 240156 WEKHIL :Product: 7-day Space Weather Highlights :Issued: 2024 Jun 24 0141 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # https://www.swpc.noaa.gov/content/subscription-services # # 7-day Space Weather Highlights # Highlights of Solar and Geomagnetic Activity 17 - 23 June 2024 Solar activity ranged from low to high levels. Region 3723 (S18, L=011, class/area=Dao/150 on 23 Jun) produced the strongest event of the period, an impulsive M9.3/1b flare (R2-Moderate) at 23/1301 UTC. Region 3719 (S15, L=067, class/area=Dao/230 on 23 Jun) also produced an R2 event with an impulsive M5.7/1b flare at 20/2316 UTC. 12 other low-level M-class (R1-Minor) events were observed from various regions throughout the week. No Earth-directed CMEs were identified with any of the flare events. Other activity included a Type-II radio sweep on 17 Jun and an additional Type-II radio sweep on 22 Jun. Both radio sweeps were associated with eruptive activity that was not on the Sun-Earth line. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the summary period. No significant geomagnetic field activity was observed during the summary period. Quiet to unsettled levels throughout week. Solar wind conditions were influenced by the onset of a postive polarity CH HSS which increased wind speeds to peak near 600 km/s on 18 Jun. Wind speeds then steadily decreased to a low of 300 km/s late on 22 Jun. A weak transient feature was observed on 23 Jun with a southward Bz of -10 nT observed, but combined with the slow wind speeds, only unsettled levels were observed.
