Scientific paper

High-resolution low-noise spectra of the OI and Ca II near-infrared
lines in Vega were obtained in 1977 and 1978. The violet-shifted
emission components discovered by Johnson and Wisniewski are not
detected. The absence of the emission lines suggests that either Vega is
a subtle variable or the emission lines were of instrumental origin.
