PRELIMINARY PHOTOMETRIC ANALYSIS RESULTS OF THE VARIABLE STAR TIC 166672575
This article presents the results of the photometric analysis of the TIC 166672575 obliterating variable star system from the Maidanak Observatory and TESS observations. Based on the MAO and TESS observation data, it was determined that the orbital period of this system is 0.1929278962 days. When the observation data were analyzed separately, the difference between the rotation periods was 3 seconds. This result showed a high agreement between our and the space telescope observation results. The asymmetry in the brightness curves of the TIC 166672575 star system indicates the presence of signs of the O’Connell effect
