Abstract
The variability of V2197 Cyg (NSVS 5761314, TYC 3167-1279-1), amongst many oth-ers, was discovered photographically by Margoni & Stagni (1984, hereafter M&S) who gave coordinates, magnitude ranges in B and V , finder charts for all 99 stars, elements (epoch, period), and preliminary light curves for about half the stars (but not for V2176 Cyg, their #58). Andronov et al. (1993) performed U, B, V, R , and I photometry of this and three other M&S stars; they went on in Andronov et al. (1994) to identify the system as an eclipsing variable, also giving the elements (including period = 0.46771 d) and eclipse duration. Skiff (1997) identified the M&S variables with those in the IRAS and GSC catalogues. Hoffman et al. (2008) provided an updated period, quoted 2MASS colours, and classified the system as β Lyrae. Since then, there have been a number of eclipse timings but no light curve analysis. examine difference O
