Broadband Stokes I spectrum for STARLINK-31034, stacked along its trajectory across the NenuFAR FoV. The top panel shows the apparent flux density across the full NenuFAR observing frequency range, and the bottom panel provides a zoomed-in view in which the apparent flux density ranges from 0 to 50 Jy to highlight details of the spectrum outside the peak frequencies. In both panels, the radio-astronomy-protected frequency bands (37.5–38.25 MHz and 73–74.6 MHz) are shaded in red.
