Description:
Three spectra of HD182308 (HR 7361) and four spectra of HD178065
(HR 7245) were obtained from 1989 to 1990 with the Main Stellar
Spectrograph of the 6-m telescope at the Special Astrophysical
Observatory and with the Coude spectrograph of the 2-m telescope of
the Rozhen Observatory of the Bulgarian Academy of Sciences. Spectra
were obtained in the range of 3700-4900A with inverse dispersion of 9
A/mm. Spectral resolution was close to 0.25A. Elemental abundances of
two HgMn stars, HD 178065 and HD 182308, were found.
