Four nebular spectra from NOT for SN 2020jfo are compared with the nebular model for a 12 M⊙ explosion. The model is scaled by the ratio of 56Ni masses in SN 2020jfo (0.025 M⊙) and the model (0.062 M⊙), as well as a factor of 0.5 to account for a significantly lower degree of gamma-ray trapping in SN 2020jfo. The most conspicuous emission lines are marked: [Mg I] λ4571, [O I] λ5577, [O I] λλ6300, 6364, NaI D, Hα, [Fe II] λ7155, [Ni II] λ7378, [Ca II] λλ7291, 7323, and the Ca II NIR triplet.
