Complete normalized MIKE/Magellan Clay spectra of SN 2024ggi. The black and red spectra were obtained, respectively, at 26.6 h and 33.8 h after the SN’s first light. Vertical lines mark the main emission features in the spectra, horizontal dotted gray lines mark the telluric absorption features, and horizontal dotted purple lines mark the Na I D and Ca II H&K absorption lines. The spectra show strong emission lines of H I, He I, He II, N III, N IV, C III, and C IV. The top panel shows the spectra obtained by the blue arm of the spectrograph, and the three other panels show the spectra obtained along the red arm.
