Correction to the report of AT 2019tau: Serveral 40-s and 300-s survey images (limiting mag about 19.0 and 20.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Oct. 23.64978, 2019, using a unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). We confirmed there was no possible supernova in NGC 1334. We're terribly sorry for our mistake.
