Located approximately {{convert|18.3|pc|ly}} distant,[1] the stellar remnant is a ZZ Ceti variable, varying by 0.02 apparent magnitudes from the mean of 13.00.[1] Observational historyThis star was first noticed during a survey for high proper motion stars by Henry L. Giclas, at Lowell Observatory, who listed it as a suspected white dwarf.[15] The white dwarf designation was confirmed spectroscopically in 1970 by astronomer Jesse L. Greenstein of the California Institute of Technology.[16] References1. ^1 2 {{cite web|url=http://www.aavso.org/vsx/index.php?view=detail.top&oid=38498 |title=PY Vulpeculae|author=VSX|date=4 January 2010|work=AAVSO Website|publisher=American Association of Variable Star Observers|accessdate=19 October 2014}} [3][4][5][6]2. ^{{Cite journal | doi = 10.1088/0004-637X/743/2/138| title = A Spectroscopic Survey and Analysis of Bright, Hydrogen-Rich White Dwarfs| journal = The Astrophysical Journal| volume = 743| issue = 2| pages = 138| year = 2011| last1 = Gianninas | first1 = A.| last2 = Bergeron | first2 = P.| last3 = Ruiz | first3 = M.
