Abstract
We present the photometric investigation of the newly discovered magnetic cataclysmic variable (polar) 1RXS J184542 during four months in 2012. We used the CCD observations in R-band obtained with the 0.5-m ARCSAT telescope at the Apache Point Observatory. It was found that during this time the object changed its relatively high accretion state to the low one. There was a two-pole accretion at the high state and one-pole accretion at the low state.
