  The defining characteristic of Z Cam stars are standstills in their light
curves. Some Z Cams exhibit atypical behaviour by going into outburst from a
standstill. It has previously been suggested that UY Pup had been a Z Cam star,
but it was ruled out due to its long-term light curve. However, in December
2015 UY Pup went into outburst and unexpectedly entered into a short standstill
instead of returning to quiescence. Furthermore, UY Pup exhibited additional
unusual behaviour with two outbursts detected during its standstill. After this
standstill UY Pup made a brief excursion to a quiescence state and slowly rose
to a longer and well-defined standstill, where it again went into another
outburst. Through comparative analysis, research, and observational data of UY
Pup it is evident and thus concluded that it is indeed a Z Cam star, in which
renders it to be one of only four known anomalous Z Cam stars.
