La Parola (INAF-IASFPA) report on behalf of a larger collaboration: We observed at the transient AT2019wxt (PS19hgw; McBrien et al., GCN 26485) using the Large Monolithic Imager (LMI) on the 4.3m Lowell's Discovery Channel Telescope (DCT) at Happy Jack, AZ. Observations started on December 20, 02:43:34 UT with SDSS g,r,i,z filters. We detected the source with the following preliminary magnitudes: Start Time Exposure Filter Magnitude (JD) ------------------------------------------------------- 58837.114 3x150 r' 19.43 +- 0.02 58837.120 3x150 i' 19.62 +- 0.01 58837.126 3x150 z' 19.58 +- 0.03 58837.126 3x150 g' 19.86 +- 0.02 ------------------------------------------------------- Magnitudes are in the AB system and are calibrated are calibrated against SDSS catalog. We thank the staff of the Discovery Channel Telescope in particular Casey Kyte, Stephen Levine and Ishara Nisley for assistance with these observations.
