Gallery of Hα (first column), Hβ (second right), Hγ (third, right), and Hδ (far right) line profiles from the NOT observations. From top to bottom: day 55, 76, 106, and 152. Note the extreme blending between Hγ and [O III] 4363 Å throughout the sequence. In addition, the [N II] 6548, 6583 Å lines were marginally visible in the wings of the Nov. 21 Hα profile. The spikes are unremoved cosmic ray hits.
