We present time-resolved photometry of the cataclysmic variable ( CV ) PTF1J2224 + 17 obtained during 4 nights in October 2018 and January 2019 from Inastars observatory .
The object is variable on a period of 103.82 min .
Archival Catalina Real-Time Transient Survey ( CRTS ) , PTF , and ZTF-data show frequent changes between high and low states .
Based on its photometric properties and the cyclotron humps in the identification spectrum the object is certainly classified as an AM Herculis star ( or polar ) with a likely magnetic field strength of B \sim 65 MG. Its accretion duty cycle was estimated from nine years of photometric monitoring to be about 35 % .
