The eclipse phenomena, known since historical times (although the time . of minimum brightness was first measured by Montanari on 8 Nov 1670) . was first explained as an eclipsing binary by Goodericke as early as . 1782. According to R.G. Aitken, this was verified when it was noted as A__1935f the second spectroscopic binary based on photographic spectra . obtained by Prof. H.C. Vogel at Potsdam in November, 1889. Belopolsky . discovered a variation in the radial velocity with a period of order . 1.8 years, later resolved by Labeyrie and his speckle camera in 1973; Lab1974 the magnitude difference is about 2.5. . The binary, a radio and X-ray source, is triple (and possibly . quadruple, but the variation with the 32 yr period is more probably an . apsidal rotation of the eclipsing pair). .

Msn1998a This complex multiple system has had numerous identification errors . due to various difficulties. The diagram of Lewis in his catalog of L__1906b the Struve pairs, which seemed a good first step, was hampered by the . quadrant error of the pair he designated Ca. This quadrant error was . repeated in the ADS, IDS, and in earlier editions of the WDS. In the . ADS (where this pair is listed as #2984, but note that #2989 is part . of this system, too) the errors multiplied. The pair Holmes AF (WDS . designation HLM 3AF) is apparently the same as STF 485Ac. Inspection . of scanned images of this region of the sky have allowed the . Hertzsprung pairs (HZG 2) whose components are given within . quotation marks in the ADS to be identified. Of the HZG pairs, the . "CD" pairing is the same as STF 484AC and the "CE" pairing is the . same as STF 484AB. The ADS note to the "AJ" pairing of HZG 2 is a . typographical error.
