2003–2017 time-series in B and V (UBV) of ρ Cas relative to the comparison star by the T3 APT project (Henry 1995, 1999). Small dots on the right in V and B are observations made by one of the present authors (EJvB; see Appendix B). The mean curves sketched through the median magnitudes of the pulsations are the LTVs, in V almost constant, in B clearly present. Some numbers in the B light curve represent pulsations quoted in the text. The sequence contains one new but weak eruption: 2013 (labelled no. 8 in the B-panel and recognizable by its deep minimum). The pulsation in 2004, labelled no. 7, has a relatively deep minimum, but is not an eruption episode. Spectral temperatures were derived by Klochkova et al. (2014) between JD 24 54168 and JD 24 55819.
