1896 Harvard Coll. Observatory Circular No. 11. Professor Solon I. Bailey has found that the star μ1 Scorpii is a spectroscopic binary.
1930 R. H. Baker Astron. viii. 338 Some examples of spectroscopic binaries among the bright stars are: Capella, Spica, Castor, β Aurigae and Algol.
1975 Sci. Amer. Mar. 28/2 The normal star associated with Cygnus X-1 is a single-line spectroscopic binary with a period of 5·6 days. The term spectroscopic here means that the presence of two stars is indicated by a periodic Doppler shift of the spectral lines of at least one of the stars as they revolve around a common center of gravity.

Astronomy. Of the sky, atmospheric conditions, etc.: sufficiently clear of cloud or humidity to permit astronomical observation using a spectroscope.Contrasted with photometric, which indicates a greater level of visibility.

1981 Q. Jrnl. Royal Astron. Soc. 22 267 A spectroscopic hour was one when the darkness, humidity and wind speed conditions were as above [i.e. assessed as photometric] but the extinction or obscuration limits were exceeded.
1992 Revista Mexicana de Astronomia e Astrofisica 24 179 From January 1984 to December 1991, 56.7% of the nights were of ‘photometric’ quality and 80.4% were of ‘spectroscopic’ quality.
