Aktivitas Matahari dapat menghasilkan flare akibat rekoneksi medan magnet di atmosfer Matahari. Salah satu peristiwa ekstrem pada Siklus Matahari 24 adalah flare kelas X9.3 yang terjadi pada 6 September 2017 di Active Region (AR) 12673. Penelitian ini bertujuan menganalisis karakteristik temporal flare X9.3 berdasarkan fluks X-ray (0,1–0,8 nm) serta respons lingkungan dekat Bumi melalui fluks proton (>10 MeV), Total Solar Irradiance (TSI), dan Total Electron Content (TEC). Data GOES-15, OMNIweb, dan LISIRD dianalisis menggunakan metode deret waktu dan cross-correlation pada periode 5–10 September 2017. Hasil menunjukkan fluks X-ray mengalami peningkatan sebesar 764,9% dari 5 hingga 6 September 2017 dan mencapai puncak pada 12:02 UT. Berdasarkan hasil cross-correlation, fluks proton dan TSI menunjukkan delay masing-masing sebesar 4,46 jam dan 8,48 jam, sedangkan TEC menunjukkan peningkatan setelah kejadian flare. Hasil penelitian menegaskan adanya keterkaitan temporal antara flare Matahari dan respons lingkungan dekat Bumi serta menunjukkan bahwa parameter X-ray, proton, TSI, dan TEC dapat digunakan sebagai pendekatan validasi dalam analisis cuaca antariksa.
