Meinunger (1966) classified it as an eclipsing binary with a period very close to 1 day, noting however that the period and derived minima times were uncertain due to the low variability amplitude. As of July 2011, the O C gateway (Paschke Brat 2006; Paschke 2009) lists, in addition to Meinunger's photographic data, 2 visual and 3 CCD times of minima from Paschke (1988, 1996, 2006), Stepan (1995), Br t et al. ...
