Abstract

Long-term optical monitoring of the dwarf nova OQ Car has been conducted to study the previously unknown behavior of this star system. The observations have shown OQ Car to have frequent dwarf nova outbursts and revealed the first recorded standstill of this star system. Based on this, we conclude that OQ Car is a new member of the Z Cam type of dwarf novae.
