679 FXXX06 KWNP 030156 WEKHIL :Product: 7-day Space Weather Highlights :Issued: 2025 Feb 03 0137 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 27 January - 02 February 2025 Solar activity ranged from low to moderate levels (R2-Moderate). Minor (R1-Minor) levels were observed on 27-29 Jan, 31 Jan and 01-02 Feb. Moderate (R2-Moderate) levels were observed on 31 Jan and 02 Feb. Region 3976 (N13, L=001, class/area Ekc/260 on 02 Feb) produced 31 C-class flares and 2 M-class flares, the largest an M2.6 at 27/0812 UTC. Region 3977 (N19, L=002, class/area Cao/120 on 02 Feb produced 10 C-class flares and 6 M-class flares, the largest an M5.1 at 02/1404 UTC. Region 3978 (N11, L=350, class/area Dai/200 on 02 Feb) produced 5 C-class flares and 1 M-class flare, the largest an M6.7/1n at 31/1406 UTC. Associated with this event was a 270 pfu 10cm burst and a 673 km/s Type II sweep. Region 3981 (N05, L=338, class/area Dsi/190 on 02 Feb) produced 10 C-class flares and 4 M-class flares, the largest an M4.1 at 02/2324 UTC. All other active regions were either quiet or contributed C-class events. Potential Earth-directed CMEs were observed on 29 and 31 Jan. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 02 Feb with a maximum flux of 1,653 pfu at 02/1550 UTC. Normal to moderate levels were observed on 27-31 Jan and 01 Feb. Geomagnetic field activity was at quiet to active levels. Unsettled to active levels were observed on 27-28 Jan due to weak CME effects. Mostly quiet levels were observed on 29-31 Jan. Unsettled to active levels were observed on 01-02 Feb due to positive polarity CH HSS effects. Solar wind parameters were slightly enhanced on 27-29 Jan due to weak CME effects. Greater enhancements were observed on 01-02 Feb with total field at highs of 18 nT and the Bz component reaching -17 nT at times. Wind speeds increased from about 410 km/s to about 750 km/s late on 01 Feb.
