Abstract Visual observations of DI Car
between 2001 June and 2005 August are plotted according to phase relative to
the previously published elements HJD 2438553.70 + 29.210 days. They support the suggestion that DI Car is a regular
pulsating star and confirms the variable depth of minimum brightness.
