Optical light curves of H 1145-619 from 1973 to 2015. The X-ray outbursts are indicated with dark blue arrows with lengths proportional to the outburst fluxes. First panel: V-Johnson optical light curves. Dark blue points come from the literature (Jones et al. 1974; Hammerschlag-Hensberge et al. 1980; Pakull et al. 1980), light blue points are from the ESO Long-Term Photometric Variable Project (Sterken et al. 1995), green points are from Hipparcos (Perryman et al. 1997), orange points come from ASAS-3, and the red points from INTEGRAL/OMC data. Second panel: I-band photometric points from ASAS-2 are shown. Third panel: EW for Hα (red points) and He i 6678 Å  (blue points) are shown. We included 1978 and 1985 measurements by Jones et al. (1974) and Cook & Warwick (1987), respectively, we re-analysed the observations from 1993 to 1996 published in Stevens et al. (1997), and we present in this work new data and results from 1997 to 2016. Fourth panel: V/R for the same spectra (see text) are shown.
