Caption: Figure 4.

Spectral sequence of TDE 2025abcr, with times given in rest-frame days relative to the peak date. The source exhibits a blue continuum with little apparent cooling, broad H lines, and a blended feature of He II (λ4686) and N III (λ4640). A comparison spectrum of TDE 2021mhg (M. Chu et al. 2021), a TDE belonging to the same TDE-H+He spectral subclass at a similar phase, is shown in black at the bottom of the figure. The spectral features of TDE 2025abcr resemble this and other known TDEs. The eight spectra are available in machine-readable format as the data behind the figure in a .tar.gz package.
