Sulfur lines in the Nov. 21 NOT spectrum. Top: [S II] 6716, 6730 Å lines detected from Nov. 21 compared with the [N II] 5755 Å and He II 6678 Å lines (both scaled fluxes). The 6730 Å component is in the red wing of [S II] 6716 and the absorption feature is the interstellar diffuse absorption feature at 6616 Å. Bottom: [S II] 4077 Å blended with Hδ (solid) compared with the scaled V1974 Cyg spectrum from 1992 Sep. 25 (dash, see below). For this comparison the continuum was scaled by a constant, no further corrections were applied.
