Тот же Юрий Соломонов сообщает о том, что 4 августа в 4 утра он наблюдал на расстоянии в 1 - 1.5 диска от Венеры звездочку 7-8 звездной величины, которая выглядела подобием спутника этой планеты. Он просит посмотреть, что это было по каталогу SAO или Гипархус.

Если посмотреть в SkyMap, получается, что около 2 ч. Московского летнего времени Венера проходила примерно в 0.5' от переменной звезды TV Gem.

Dec: +21њ 52' 05.663"

Standard errors of the equatorial coordinates (epoch J1991.25)

RA: 0.0068 arcsec
Dec: 0.0042 arcsec

Astrometric reference flag: This is a recommended astrometric reference star, having good Tycho astrometric quality, and not recognised as double.

Trigonometric parallax: -0.01280 arcsec
Standard error of the parallax: 0.00740 arcsec

Proper motion components (epoch J1991.25, ICRS)

RA: +0.00550 arcsec/yr
Dec: +0.00010 arcsec/yr

Standard errors of the proper motion components

RA: 0.0056 arcsec
Dec: 0.0044 arcsec

Number of accepted data points: 106
Goodness-of-fit parameter, F2: 1.49

Hipparcos catalog number: 29416

Astrometric quality flag: 2 (very high).
Signal-to-noise ratio of the star image, Fs: 10.7

Source of astrometric data: Standard data processing.

Photometric Data

Mean Bt magnitude: 9.600
Standard error: 0.022

Mean Vt magnitude: 7.056
Standard error: 0.007

Source of photometric data: The Bt,Vt data are de-censored mean values derived from the de-censoring analysis from the (normal) photometric processing for faint stars.

Johnson B-V colour index: 2.131
Standard error: 0.020

Number of transits used in mean photometry: 84
Vt scatter, s: 0.163 mag
Vt magnitude at maximum luminosity: 6.95
Vt magnitude at minimum luminosity: 7.24

Previously known or suspected variability: The star is listed in the "General Catalog of Variable Stars, 4th edition" (P.N.Kholopov et al., Publ. Office 'Nauka', Moscow, 1985-88).

Variability of the Tycho measurements: Apparent variability in the Tycho data; this may be due to duplicity, and this flag is only set if an indication of duplicity was also found.

Unresolved duplicity status: Weak indication of duplicity, combined with indication of variability.
