What would certainly be handy is if someone could check the original reference, apparently there is a chart or photograph there: REFERENCE to a study of the star: 07912 J.Lukas, JAAVSO 4, N2, 64, 1975- 1976. REFERENCE to a chart or photograph: 07912 J.Lukas, JAAVSO 4, N2, 64, 1975- 1976. Unfortunately this particular issue of JAAVSO is not available on ADS. It would be instructive to compare the chart with one of the recent photos.
