ASAS-SN light curve of V420 Hya is shown on the left, with magnitudes in the V and g bands. The g-band observations were shifted by 0.18 mag to bring them in line with the V ones. The upper right panel shows a zoom-in region of 600 days to highlight the short-term periodicity. The lower right panel shows the g-band data folded on the best period we determined, 767.364 days, together with some phase-averaged means to illustrate the apparent ellipsoidal or eclipsing variations.
