| Résumé | The variability of V2477 Cyg (NSV 13016 = NSVS 3227395 = HD 239379 = TYC 3945–1423–1), amongst many others, was discovered photographically by Hoffmeister (1963) as part of the Sonneberg Survey (Gessner 1966). The former gave coordinates and a finder chart, described the system as a short period variable, and designated it as S 7891. Skiff (1999) identified many Sonneberg variables, amongst them S 7891, giving accurate coordinates and associating them with existing names. The first accessible elements (epoch, period) were published by Otero & Wils (2005), who also classified the system as EW, and listed the magnitude range and spectral type. Since then, there have been a number of eclipse timings, but no light curve analysis. |
