We have studied spectra of nova V1500 Cyg (1975) shortly after its optical maximum. We find that the very wide red wing of the Hε plus Caii H line blend in emission, which was invisible at maximum, appeared a few hours later. What was according to Duerbeck & Wolf (1977A&AS...29..297D) an extremely blue shifted absorption component of Hβ was also seen soon after. These observations can be understood by the presence of a continuously ejected high velocity wind, which became visible during the time of these observations. Somewhat later observations by other observers indicating emission line narrowing, can then be understood as due to a weakening of the wind at such times. The significance of the position of the blue edge of the main absorption component of Hβ and Hδ is also discussed in relation to the region where this absorption is produced.
