Abstract

 

Using minima derived from photographic observations on the plates of the Maria Mitchell Observatory and Sternberg Institute collections or found in the literature, covering a very wide range of Julian dates (2420300-2448120), we find that the eclipsing variable CF Sct, with two previously reported period values somewhat contradicting each other (31.9415 and 31.9384 days), actually shows a quite constant period of 31.94036 days over decades.
