GCN Circular 26503
Albert Kong (NTHU), Han-Jie Tan (NCU), Chow-Choong Ngeow (NCU), Wing-Huen Ip (NCU) On behalf of the Global Relay of Observatories Watching Transients Happen (GROWTH) collaborations We report the photometric measurements of AT2019wxt (GCN #26485) associated with the gravitational wave event S191213g (GCN #26402) using the Lulin One-meter Telescope (LOT) in Taiwan. The observations were conducted using g, r, i filters for 300 sec each starting at 2019-12-19 10:42:45 UT. Preliminary photometry (AB) was obtained by calibrating with the PS1 catalogue. We obtained g=19.50+/-0.04, r=19.40+/-0.03, and i=19.47+/-0.06. Compared to the Palomar observations taken 6 hours earlier (GCN #26500), AT2019wxt remains at the same brightness level. We would like to thank the staff in Lulin Observatory for helping the observations.
