Indications for the presence of a postmaximum wind of nova V1500 Cyg

We have studied spectra of nova V1500 Cyg (1975) shortly after its optical maximum. We find that the very wide red wing of the H epsilon plus Ca II H line blend in emission, which was invisible at maximum, appeared a few hour s later. What was according to Duerbeck & Wolf (1977) an extremely blue shi fted absorption component of H beta was also seen soon after. These observa tions can be understood by the presence of a continuously ejected high velo city wind, which became visible during the time of these observations. Some what later observations by other observers indicating emission line narrowi ng, 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 c omponent of H beta and H delta is also discussed in relation to the region where this absorption is produced.
