Preliminary results of observations of the UV spectra of weak stars (9th to 12th magnitude) in the 2000 to 5000 A range made from the Orion-2 observatory on board Soyuz-13. About 10,000 spectrograms of more than 3000 stars were obtained over 5 days with a meniscus telescope and objective prism. Data are presented for a group of about 20 previously uncataloged stars detected around Capella, in Auriga; more than 20 Type B stars in Vela; emission stars with spectral lines assigned to such metals as iron, chromium, nickel, cobalt, and others; interstellar absorption at 3000 to 2000 A in the spectrum of SAO 040183, probably due to blocking of emission lines excited in the stellar gaseous envelope; the doublet of 2800 Mg II in stellar spectra; the chromospheres of cold stars; and the UV spectrogram of the planetary nebula NGC II 2149. The possibility of classifying stars according to their continuous spectra is discussed.
