Paek (SNU), Joonho Kim\n(SNU), Sungyong Hwang (SNU), Bomi Park (SNU), Sophia Kim (SNU), Changsu\nChoi (SNU),  Hyung Mok Lee (KASI), on behalf of a larger collaboration\n\nWe observed the transient AT2019wxt (PS19hgw; GCN 26485) using Seoul\nNational University Astronomical Observatory (SAO) 1-meter telescope at\nSeoul, South Korea. The observations began on December 19, 09:12:38 UT with *B,\nV, R, I* filter taking 180s for each image. After the calibration with PS1\ncatalog, we conducted image stacking and host galaxy subtraction using PS1\ntemplates. The source is detected in *R, I* images. 5-sigma limit image\ndepth for point source is presented for *B, V* imaging.\n\nStart time  [MJD]                    Filter\n magnitude [AB]\n----------------------------------------------------------------------------------\n58836.384                                 B                             <\n18.730\n58836.404                                 V                             <\n18.833\n58836.424                                 R\n19.464+/-0.118\n58836.444                                 I\n19.469+/-0.128\n\nOur photometry results are consistent with GCN 26503.\n\n*Lim, Gu*\n\n\nPh.
