886 FXXX06 KWNP 100156 WEKHIL :Product: 7-day Space Weather Highlights :Issued: 2024 Jun 10 0134 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 03 - 09 June 2024 Solar activity ranged from moderate to high levels. Region 3697 (S18, L=350, class/area=Fkc/350 on 03 Jun) was the most active sunspot region this period and produced 14 (R1) Minor events and two R2 (Moderate) events; the largest of which was a long-duration M9.7/1f flare at 08/0149 UTC. Following the M9.7 flare, a SEP event commenced and a partial halo, Earth-directed CME was produced. Region 3697 also produced an M6.1/2b flare at 06/1506 UTC. Regions 3695 (N27, L=030, class/area=Cao/50 on 03 Jun), 3703 (S08, L=327, class/area=Dac/200 on 07 Jun), and 3709 (S10, L=218, class/area=Cai/140 on 09 Jun) each produced a single R1 event. Solar radiation storm conditions were observed on 08-09 Jun, following the long-duration M9.7 flare at 08/0149 UTC from Region 3697. The greater than 100 MeV proton flux exceeded 1 pfu beginning at 08/0225 UTC, reached a peak flux of 8 pfu at 08/0625 UTC, and decreased below the 1 pfu threshold at 08/1455 UTC. The greater than 10 MeV proton flux exceeded the S1 (Minor) event threshold beginning at 08/0255 UTC, reached a peak flux of 1,030 pfu at 08/0800 UTC (S3/Strong), and decreased below S1 levels at 09/2125 UTC. The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the period. Geomagnetic field activity reached G1 (Minor) storm levels on 03 Jun due to positive polarity CH HSS influences. Quiet and unsettled levels were observed on 04-06 Jun. G2 (Moderate) storm levels were observed on 07 Jun, and active levels were observed on 08 Jun, due to CME activity. Quiet conditions prevailed on 09 Jun.
