Detection of the X5 flare occuring on 2025/11/11. The soft and hard X-rays fluxes are represented in black (full and dashed lines respectively) and the phase from NRK in green. The red vertical lines represent the first detections of this flare, and the blue vertical lines the moment at which the flux estimation reaches an M5 threshold. Full lines show the time detection with δ t = 60 s and dashed lines those with δ t = 15 s. The blue dotted line is the time of the issue of the SWPC alert for the M5 threshold.
