  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 ~ 65 MG. Its accretion duty cycle was estimated from nine
years of photometric monitoring to be about 35 %.
