Abstract
Combining visual observations of semiregular variables with measurements of them using a photoelectric photometer is discussed, and then demonstrated using data obtained for the bright, southern semiregular variable θ Aps. Combining such observations is useful in that it can provide a more comprehensive set of data by extending the temporal coverage of the light curve. Typically there are systematic differences between the visual and photometric datasets that must be corrected for.
