019 FXXX06 KWNP 100126 WEKHIL :Product: 7-day Space Weather Highlights :Issued: 2025 Mar 10 0111 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 March 2025 Solar activity was moderate on 05 and 07 March with two M1 flares, neither had any significant radio or CMEs associated. The rest of the period was at low levels. No significant CMEs were observed. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 04 March. Low to moderate levels were observed for the rest of the period. Geomagnetic field activity reached moderate levels on 09 March due to negative polarity CH HSS influences. Solar wind speeds reached peaks of near 675 km/s. Minor storm levels were observed on 08 March in response to the same CH HSS effects. Active levels were observed late on 04 March into early on 05 March due to suspected weak CME influences. Quiet to unsettled conditions prevailed for the remainder of the period.
