Contribution

It provides the first detailed photometric analysis and orbital period measurement of 1RXS J174320.1-042953, confirming its classification as a magnetic cataclysmic variable (polar).

Findings

Identified the orbital period as 0.0866 days (2.08 hours).

Confirmed the system as a magnetic cataclysmic variable (polar).

Observed large brightness variations between low and high states.

Abstract

We report on the photometric analysis of the poorly studied cataclysmic variable in Ophiuchus 1RXS J174320.1-042953 (DDE 11). Results of the monitoring with the Bradford Robotic Telescope (BRT) are presented, as well as the time-resolved photometry obtained at Montecatini Astronomical Centre. The long-term behavior of J1743-0429 shows it is a magnetic cataclysmic variable (polar) with the large difference between the low and high states. The orbital period obtained from our observations is 0.0866d, or 2.08hr, close to the lower boundary of the period gap of cataclysmic variables.
