We observed the transient AT2019wxt (PS19hgw; GCN 26485) using Seoul
National University Astronomical Observatory (SAO) 1-meter telescope at
Seoul, South Korea. The observations began on December 19, 09:12:38 UT with *B,
V, R, I* filter taking 180s for each image. After the calibration with PS1
catalog, we conducted image stacking and host galaxy subtraction using PS1
templates. The source is detected in *R, I* images. 5-sigma limit image
depth for point source is presented for *B, V* imaging.
