Changes in the period and light curve of W Corvi.

ODELL A.P. and CUSHING G.E.

Abstract (from CDS):

We present 14 CCD times of minima of the eclipsing binary W Corvi. With timings from the AAVSO, we confirm a period increase of 0.25 sec/century. CCD light curves between 1999 and 2003 show that by 2003, the maxima are of equal brightness (the O'Connell effect has again disappeared). The check star, contained on the same frame, shows that the comparison star used extensively in the past may be slightly variable.
