Narrow P-Cygni profiles in velocity space. Top (LRIS NIR spectra): The two upper spectra clearly show narrow P-Cygni profiles of He I 1.0830 μm with peak to peak separations of ∼150 km s−1, pointing to unshocked CSM. In the two lower (same epoch) spectra, a narrow profile in the Paβ line is tentatively detected. Bottom: Four low-resolution optical spectra centred on Hα spanning ∼10 days.
