VZ Lib: a contact binary in a ternary system [Observed: 2014 (1 session, 1 ToM), 2016 (1 session, 1 ToM), 2018 (1]
New photometric observations are presented for this contact binary in a ternary system. A total of 113 times of minimum are analyzed and are found to be in agreement with the ephemeris of Liao et al (2019).

VZ Lib: a contact binary in a ternary system [Observed: 2007-2009, 14 sessions]
Time series of this eclipsing contact binary are reported and times of minima (ToM) of the eclipses are measured. This system has a third component. From the O-C analysis of the observed ToM and of those in the literature, the orbital parameters of the third body can be derived: the orbital period is 34.8 yr and the inclination is 11.5 °.
