260 FXXX06 KWNP 290256 WEKHIL :Product: 7-day Space Weather Highlights :Issued: 2024 Apr 29 0236 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 22 - 28 April 2024 Solar activity reached high levels on 22 Apr and 24 Apr. Moderate levels were observed on 23 Apr, 25 Apr, and 27 Apr. Finally, low levels were observed on 26 Apr and 28 Apr. In total, there were 20 low-level M-class events (R1-Minor) over the past week. The strongest was an M3.6 flare at 23/0319 UTC from Region 3654 (S07, L=135, class/area=Ekc/310 on 28 Apr). Of the 24 numbered active regions observed on the visible disk, 6 produced M-class activity. Type II radio events were observed on the 22 Apr, 23 Apr, and 24 Apr. The 23 Apr event was associated with an M2.9 flare at 23/1744 UTC from Region 3645 (S09, L=226, class/area=Dki/290 on 21 Apr). The 24 Apr event was associated with a C9.4 flare at 24/1410 UTC from Region 3638 (S18, L=227, class/area=Cri/080 on 21 Apr) and was also accompanied by a Type IV radio sweep. The associated CMEs are likely to have been associated with geomagnetic activity observed at Earth over 26 Apr. The region produced numerous, small, slow-moving CMEs that were primarily directed south of the ecliptic plane over the week. An additional CME first observed ~27/1100 UTC in SOHO/LASCO C2 imagery, which originated from the vicinity of Region 3654, was analyzed and modeled. The results suggested a component along the Sun-Earth line with effects likely to be observed around 01 May. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 25 Apr. The remainder of the summary was at normal to moderate levels. Geomagnetic field activity was ranged from quiet to G1 (Minor) geomagnetic storm levels. G1 levels observed on 26 Apr are thought to be associated with transient influence from activity that occurred on the Sun several days earlier. Unsettled conditions on 27 Apr were observed the Bz component of the IMF turned northward. Active conditions were reached early on 28 Apr due to a positive polarity CH HSS. The remainder of the summary period was at quiet to unsettled levels.
