The twelve-year light curve of the nova-like cataclysmic variable HS
0506+7725 between 2006 April and 2018 November is presented. This shows that
the star spends most of the time in a normal state at magnitude ~14.7, but
multiple excursions to a fainter state at magnitude 16.0 to 17.0 were apparent.
These normal state/low state transitions of up to 2.3 magnitudes are typical of
the VY Scl subclass of CVs. The second of these fading episodes was the best
characterised as its return to normal brightness was also observed. The
complete transition lasted about 43 days. Further monitoring of this system by
amateur astronomers is encouraged to identify and characterise future low
states.
